Are you confused by couverture chocolate? You aren’t alone. I hadn’t even heard of it before I began my confectionery training. But never fear — here’s the quick and dirty on couverture chocolate for your reading pleasure.
Couverture is a type of chocolate made specifically for confectionery use. Its defining characteristic is its higher cocoa butter content (32-39% ADDED cocoa butter, on top of the cocoa butter already present in the cocoa mass). The extra cocoa butter makes couverture thinner when melted, so professionals can achieve super-thin, super-shiny bonbon shells for their confections. It also gives couverture a really smooth texture and mellow flavor — in no small part because the cocoa butter significantly dilutes the flavorful (but less creamy) cocoa bean mass.
Chocolatiers refer to the more liquid quality and easy pourability of melted couverture in terms of its viscosity — specifically, they categorize couverture as “high viscosity” chocolate. When I first started working with chocolate this confused me to no end, because in physics, the higher the viscosity, the THICKER the liquid. For some reason (maybe they were high on theobromine), chocolatiers decided to reverse that — they call chocolate that is thin and runny “high viscosity.” Clearly someone wasn’t paying attention in high school physics class!
It would be remiss of me to talk about couverture chocolate without noting that, well… it’s delicious. Especially if you like that smooth, European, vanilla-forward chocolate style. But who likes that, right? 😉
You may be wondering if you’ve ever tasted couverture, or if you would even recognize it if you saw it on a shelf, and my guess is that you would. Valrhona and Callebaut are two of the most well known couverture makers — you’ve probably heard of them. Michael Cluizel, Amedei and many others make excellent couverture too.
If you’re interested in a couverture starter kit, I recommend ordering it on Chocosphere, which has a great selection of bars and sampler packs (I love this one). Try the Valrhona classics like Manjari and Guanaja. Jivara is a great couverture milk chocolate (also by Valrhona), if that’s what you’re looking for.
If you do try any of these, please let me know what you think of them.
After this NY Times article came out last week, those of you who know me well may have guessed that it was only a matter of time before I attempted to make chocolate mousse using canned chickpea liquid.
If you’re COMPLETELY lost right now, let me back up. Chickpea canning liquid — fancy name aquafaba — has been used by vegan cooks as an egg white substitute for decades. It whips up (or so I’ve been told) into a frothy white foam that looks exactly like meringue. It would be so cool — if it worked.
I’d heard of aquafaba before, mostly as a good substitute for eggs in vegan marshmallow fluff. But, quite frankly… fluff is disgusting. So I’ve never attempted that recipe — or anything else involving canned chickpea liquid, for that matter.
And then the Times article came out, and everything changed. It looked so versatile. So magical. So… weird. I had to try it.
The Times article suggests making meringues or vegan mayonnaise with aquafaba, and maybe those would have worked better. But me being me, my mind immediately went to… chocolate mousse. Because… chocolate mousse.
I did not, however, go about this experiment in a very organized fashion. Instead, one morning last week I got up, dumped chickpea canning liquid into a bowl, added a couple spoonfuls of cocoa powder and confectionery sugar, and started whipping.
15 minutes later, I had a little foam. I kept whipping.
Nothing. Just a little froth that immediately deflated when I poured it onto a baking sheet (at this point I’d given up on mousse and was hoping to salvage the foam by making pavlova). Honestly, I couldn’t even bring myself to take a picture of the mess. It was too depressing.
So, back to the the drawing board I go.
I have a few thoughts about what to do differently next time. I could try adding cream of tartar as a stabilizer, just like you would with traditional egg whites. Another thought I had is that I might have screwed up by adding the cocoa powder early. While cocoa powder contains only trace amounts of fat, it is not fully fat free. Egg whites won’t whip up if they are contaminated by even a drop of oil, and maybe aquafaba is the same way.
If I ever master the technique, I’d like to try incorporating real chocolate into the aquafaba instead of cocoa powder. The problem with using actual chocolate in this recipe is that the chocolate will seize when it comes into contact with aquafaba because of the temperature difference. I haven’t quite figured out a solution to that issue yet, but my wheels are turning. I might be able to incorporate the aquafaba into the chocolate slowly, in several batches. If you have any other ideas, please send them my way.
Update 7/12/16: I was finally able to make a successful aquafaba mousse! Check it out here.
This two-ingredient mousse tastes like a fluffy, whipped, lightly sweetened, extremely intense chocolate bar. In a bowl. Need I say more?
Traditionally, chocolate mousses are made using cream or egg whites, and their volume and thickness is achieved by whipping air bubbles into them. This chocolate mousse, however, achieves its fluffy texture via an altogether different mechanism: the chemistry of cocoa butter.
Cocoa butter is solid at room temperature. But if you get the proportions just right, you can create a perfect mousse-like texture by adding just enough water to melted chocolate so it only partially solidifies as it cools, creating a mousse-like texture without the help of air bubbles.
I would actually classify this as a whipped water ganache rather than a mousse, if I were going to get technical about it. If you think of regular chocolate ganache as, say, a cappuccino, then water ganache is black coffee: strong, dairy free, slightly bitter and super stimulating.
Recipe: Two Ingredient Dark Chocolate Mousse
Adapted from Melissa Clark’s recipe for the New York Times
Makes one generous serving
2 oz good dark chocolate, chopped into small pieces
1.6 oz hot water(approx. 3 tbsp + 1 tsp)
Optional variations: I recommend adding a pinch of sea salt to the hot water before melting the chocolate. Alternatively, try flavoring the mixture with a few drops of peppermint oil or vanilla extract, or substituting coffee for the water to get a nice mocha flavor.
Serving recommendations: This would taste great over fresh berries, with a dollop of whipped cream or crème fraîche on top. But it’s pretty great on its own, too.
Mix the chocolate and water in a small bowl and microwave on high for 30 seconds. Stir. If the water feels hot to the touch and the chocolate is melting easily, you’re done with the microwave. If you still notice chunks of chocolate in the water, microwave the bowl for another 10-20 seconds. Whisk until the chocolate is completely dissolved and no graininess remains (this step is very important for a silky result).
Place the bowl of liquid chocolate in a shallow ice bath.
Using an electric whisk or egg beaters (an immersion blender would probably work too, although I haven’t tried it), whisk the chocolate as it cools. After a few minutes you should begin to see its texture thickening modestly.
Stop mixing and remove from ice bath once the mousse has reached the thickness of softly beaten egg whites.
Btw: If the chocolate mixture cools too much it will develop a texture like that of chocolate frosting (you can see an example of this in the picture below). If you accidentally over-thicken it, try whisking in another teaspoon of hot water.
I know, I know, enough with the gianduja already! I promise this is my last post about the chocolate-hazelnut deliciousness known as gianduja for, well… at least a week.
My recent recipe for Gianduja Crunch Truffles included directions for making your own gianduja (a wholesome, less processed version of Nutella) at home. Shortly after publishing that post, I was contacted by a happy reader who had made gianduja for the first time. He was spreading it on toast and mixing it into everything imaginable (he warned against mixing it into coffee — seems like good advice!). Anyway, the reader loved homemade gianduja so much that I was inspired to make it easier for readers to locate my gianduja recipe without sifting through lengthy instructions on truffle-making and chocolate tempering.
Notes about this recipe:
I love this gianduja recipe because it’s so simple and so wholesome. If you’ve ever looked at the ingredients on a jar of Nutella, you’re aware that there’s nothing healthy about that mixture of sugar and palm oil (ew). So it was important to me that this recipe include only the highest quality ingredients: roasted nuts and super dark chocolate. No fillers, and no added sugar (the only sugar in this recipe is what’s already in the dark chocolate).
A quick note on substitutions: If you want to eliminate sugar from this recipe completely, try substituting 8 oz. unsweetened chocolate plus your sugar substitute of choice for the dark chocolate. After blending the other ingredients, add the sugar substitute to the food processor slowly, tasting until it’s sweet enough. As I’ve mentioned before, I personally like stevia as an alternative sweetener, and stevia works well to sweeten nut butters so it might actually be a good choice for this recipe (I’ve never tried it though, so don’t quote me on that). Other sugar substitutes (honey, xylitol) and noncaloric sweeteners (sucralose, aspartame) would likely work as well. You could also substitute cocoa powder and sugar (or a sugar substitute) for the dark chocolate in this recipe — if you try this, please let me know how it tastes!
So here you go: a super simple recipe for making your own delicious, addictive, healthy chocolate-hazelnut spread using nothing more than your oven/toaster, a microwave and a food processor or Vitamix.
Recipe: Dark Chocolate Hazelnut (Gianduja) Spread
Makes 13 oz gianduja (about 1 2/3 cups)
5 oz dark chocolate (60-70% cocoa*) chopped into small pieces (can substitute bittersweet chocolate chips, or even milk chocolate for a sweeter gianduja)
8 oz whole hazelnuts
* The higher the % cocoa, the lower the relative % sugar in your gianduja
To roast the nuts: On a baking tray on the center rack of your oven, toast the hazelnuts at 350 degrees Fahrenheit for 15-20 minutes, stirring occasionally until they’re fragrant and golden brown (but not burnt). Wrap them in a clean dish towel to cool on the counter. Once cool, use the towel to rub off the skins, removing any stubborn skins with your fingers (leaving the skins on won’t ruin the gianduja, but they do taste a little bitter).
To melt the chocolate: Melt 8 oz dark chocolate in the microwave. To do this without burning the chocolate, place the chopped chocolate pieces in a plastic container (glass or ceramic will retain too much heat) and microwave for 2 minutes, stirring every 45 to 60 seconds. Continue microwaving at 10 second intervals, stirring well after each interval. To avoid burning it, stop when the chocolate is 80% melted — its residual heat will melt the remaining solid chocolate pieces as you continue to stir. The whole process should take less than 5 minutes.
To make the gianduja: In a food processor or Vitamix, blend the hazelnuts into a paste, scraping down the sides as needed. The consistency should be like that of creamy peanut butter. Add the melted chocolate and blend until creamy.
Store the gianduja in a tightly sealed container away from sunlight for 1-2 months, or in the refrigerator for 6-12 months.
Note: if you store gianduja in the fridge, you’ll need to microwave it (or leave it at room temperature for a couple of hours) to bring back its soft, spreadable consistency.
This truffle was inspired by Perugina’s Baci, those addictive Italian chocolate-hazelnut confections that have started showing up in American supermarkets everywhere. I wanted to add some texture to the classic round truffle by pressing a whole hazelnut into its center. The result is delightful; the hazelnut provides a wonderful textural contrast to the otherwise uniform creaminess of the gianduja.
And since we were talking about sugar-free chocolate last week, here’s another cool thing about these truffles: other than what’s already in the chocolate, there’s no added sugar in these. The ingredients are nuts and dark chocolate. That’s it. As noted in a previous post, homemade gianduja is so much more wholesome than Nutella. You could almost consider these truffles… healthy?
I decorated the truffles using a piping bag filled with tempered milk chocolate. It’s a really fun technique — I felt like I was in kindergarten art class. But feel free to skip this part. In fact, you can make these truffles without any tempering at all! Dip the truffle centers in untempered chocolate (melted in the microwave as described below) and then roll them in chopped hazelnuts, sugar, crushed corn flakes or whatever else you think of. Nobody will know the chocolate shell is untempered if it’s hidden this way.
Btw, this recipe can easily be doubled or halved. The important thing is that there be a 1:1 ratio of chocolate to hazelnuts in the gianduja filling. If you’re on the fence, I would make a larger batch rather than a smaller one… gianduja keeps for several months at room temperature and much longer in the fridge, so having some extra around to spread on toast or drizzle on pancakes wouldn’t be the worst thing in the world…

Gianduja Crunch Truffles
Makes approximately 30 truffles.
Shelf life: at least two months at room temperature; up to six months in the refrigerator.
Gianduja crunch centers:
8 oz dark chocolate, chopped into small pieces (I used DeZaan’s 64% dark couverture, but any bittersweet chocolate will work — or use milk chocolate for a sweeter truffle)
12 oz whole hazelnuts
8 oz tempered dark chocolate for enrobing (optional)
2-3 oz tempered milk chocolate for decorating (optional)
You can also can skip the chocolate shells entirely and roll the centers in chopped hazelnuts, cocoa powder, cocoa nibs, crushed corn flakes, sugar, ground coffee beans — be creative!
To roast the nuts: On a baking tray on the center rack of your oven, toast the hazelnuts at 350 degrees Fahrenheit for 15-20 minutes, stirring occasionally, until they’re fragrant and brown but not burnt. Wrap them in a clean dish towel to cool on the counter. Use the towel to rub off the skins, and remove any stubborn skins with your fingers. Leaving the skins on won’t ruin the gianduja, but I think they taste a little bitter.
To melt the chocolate: Melt 8 oz chopped dark chocolate in the microwave. To do this without burning the chocolate, place it in a plastic container (glass or ceramic will retain too much heat) and microwave for 2 minutes, stirring every 45 to 60 seconds. Stir well.Continue microwaving at 10 second intervals, stirring well after each interval. To avoid burning the chocolate, stop when it’s 80% melted — the residual heat of the chocolate will melt the remaining pieces as you stir. The whole process should take less than 5 minutes.
To make the gianduja filling: Reserve 4 oz toasted hazelnuts. In a food processor, blend the remaining 8 oz hazelnuts into a paste. The consistency should be like that of peanut butter. Add the melted chocolate. Blend until creamy.
You can stop here if you want, storing the gianduja in a tightly sealed container away from sunlight for 1-2 months, or in the refrigerator for 6 months or more. Note that if you store gianduja in the fridge, you’ll need to leave it at room temperature (or microwave it) to bring it back to a soft, spreadable consistency.
Or, continue on to the next step to make truffles with it.
Note: If the gianduja is too soft immediately after making it, refrigerate for 30-60 minutes before rolling it into balls. Just remember it’s very important to bring the balls to room temperature before enrobing them in tempered chocolate.
To enrobe the centers: Melt and temper the remaining 8 oz chocolate. One at a time, drop each truffle into the chocolate and scoop it out with enrobing forks (a kitchen fork will work in a pinch). Place them on parchment paper to set. If you chose to use untempered chocolate for this step, you’ll need to roll the balls in a bowl of chopped hazelnuts (or your coating of choice) before the chocolate has a chance to set.
To decorate the enrobed truffles: Melt and temper* the milk chocolate and pour it into a large plastic sandwich bag. Twist the end of the bag to push the chocolate into one of the bottom corners. Using scissors, snip off the tip of the corner (ta-da — you have a piping bag!) and, squeezing from the twisted end of the bag, pipe milk chocolate stripes, swirls or dots onto the truffles. Work on parchment paper for easy cleanup. Fun, right?
*Milk chocolate should be tempered at a slightly lower temperature than dark chocolate, so my seeding instructions won’t be that helpful for this. For now I recommend you check out the instructions for tempering milk chocolate on Ecole Chocolat’s website.
A little while back I wrote about the history of traditional Italian gianduja and its more modern, spreadable cousin. Since that post, a couple of readers have asked me where they can buy gianduja, since all they’ve been able to find at their local supermarket is Nutella.
You have three options if you’re trying to locate real gianduja in North America. First, you can probably find it at a specialty chocolate retailer in your city or town. To find the closest retailer, search on chocomap.com or download the Find Chocolate! app on your device. Yes, there’s an app to help you find chocolate!
Another option: you can search the shelves of a European food import store (think Dean & Deluca).
And finally — and this is my own preferred method — you can buy gianduja online.
Why buying gianduja online makes sense:
Besides the fact that it’s clearly awesome to buy chocolate without leaving the house or speaking to another human being, I like buying gianduja online because the selection is much, much better online than anything you’ll find in a brick and mortar shop — this I promise. I’m guessing the average specialty Italian food importer will carry one or two types of gianduja. In contrast, online retailers carry dozens.
Favorite online gianduja retailers:
For starters, Amazon carries a respectable number of gianduja products of both the solid and spreadable varieties, so it may be a good place to start. I recommend also checking out the selection at Chocosphere and World Wide Chocolate. If you live outside the U.S. and know an online retailer that delivers to your region, I would love to know about it — send me a link!
Europeans may want to order directly from one of the acclaimed Italian gianduja makers’ websites, such as Venchi’s. Or even better, find an excuse to go to Turin (remember that obscure work conference your boss mentioned a while back…?) and pick up gianduja from one of the many specialty shops scattered around the city. I hear Turin is lovely this time of year…
Want a more hands-on way to get your, um, hands on some gianduja?
Rather than buying gianduja, I highly recommend you try making it at home in your food processor. After seeing how easy it is, you may never buy the ready-made kind again.
See my recipe in the next post… But in the meantime, I leave you with this picture of deliciousness from Sarah Reid’s Flickr page.
I dare you to stare at this for 5 seconds without your mouth watering… 🙂
To date, sugar-avoiders have had very few options when it came to chocolate. Most of the sugar-free chocolate on the market relies on sugar alcohols (erythritol, xylitol, mannitol, etc.) for its sweetness. Sugar alcohols are notorious for causing GI distress in some people, making chocolates sweetened with them not worth the discomfort for those affected. But stevia, an all-natural calorie free sweetener, doesn’t cause GI issues and doesn’t affect blood glucose levels the way some artificial sweeteners are purported to do.
That said, stevia tastes terrible in chocolate. I’ve tried adding it to unsweetened chocolate several times, and on a good day the results taste like aluminum.
Which is unfortunate, because I really WANTED to like stevia-sweetened chocolate. Not because I worry about my sugar intake, but because I grew up eating a lot of stevia (health-obsessed family + diabetic parent = lots of weird food in the house) and have grown to appreciate its gentler, lingering sweetness in foods like oatmeal or plain yogurt. It’s the perfect sweetener for coffee. So why not chocolate?
It turns out, the answer to that question is complicated. One of the interesting things I’ve learned while working for a local small-batch chocolate maker is that sugar does more for chocolate than just sweeten it. It also affects chocolate’s viscosity, texture and flavor intensity.
Sugar’s effect on chocolate’s viscosity:
Adding sugar to chocolate reduces the chocolate’s relative cocoa butter content, which means adding sugar will thicken your chocolate. Cocoa nibs are about 50% cocoa butter, and most chocolate makers add additional cocoa butter to facilitate molding and enhance texture. But add 30% sugar to that chocolate and your total cocoa butter percentage will fall significantly. This leads to thicker chocolate that many chocolatiers may find unsuitable for enrobing confections.
Sugar’s effect on chocolate’s texture:
Also, part of the art of making chocolate is figuring out the right time to add the sugar. The cocoa beans are ground by granite rollers in a melangeur for several days, and sugar is added at some point along the way. Added too late, and — depending on the chocolate maker’s refining equipment — large sugar particles may result in a gritty texture (interestingly, Taza Chocolate leaves large sugar particles in its chocolate on purpose, and the texture of their chocolate is quite unique).
Side note: one thing I’m still trying to figure out is what happens if sugar is added too EARLY in the grinding/refining process? Why don’t chocolate makers just add sugar at the very beginning, as soon as the nibs have liquefied in the melangeur? Is it possible for sugar particles to become TOO small?
Sugar’s effect on the intensity of chocolate’s flavor:
Generally, in dark chocolate anyway, the lower the percentage of sugar, the higher the percentage of cocoa mass. At least theoretically. The thing is that most chocolate makers also add additional cocoa butter to their chocolate, and the “cocoa solids” percentage stated on chocolate bar wrappers includes the combined weight of the cocoa mass AND the added cocoa butter. So a 70% dark chocolate could be 30% sugar and 70% cocoa mass (known in the industry as “two-ingredient chocolate”). Or it could be 30% sugar, 20% cocoa butter, and only 50% cocoa mass. Suddenly that chocolate isn’t sounding so dark, is it?
Earlier in this post you learned that sugar makes chocolate thicker by reducing its relative cocoa butter percentage, and chocolate makers often add extra cocoa butter in order to thin it out again (and sometimes to improve its texture). Given that cocoa butter has very little actual chocolate flavor, the more additional cocoa butter in a chocolate, the less intense its flavor.
“Couverture” chocolate — the chocolate used by chocolatiers to make bonbon shells and enrobe truffles — by definition must contain over 31% added cocoa butter. So that means that a 65% dark couverture chocolate is likely made from 35% sugar, at least 31% added cocoa butter and, at the very most, only 34% cocoa mass (most likely less because most cocoa makers also add soy lecithin). 34% cocoa mass does not an intense chocolate make.
So as you can see, sugar interacts with other ingredients in chocolate in complex ways by displacing cocoa butter and affecting texture. Chocolate makers have been trying to tweak processes and recipes for hundreds of years. Replacing sugar with a sweetener that has a completely different chemical composition is complicated, requiring multiple adjustments along the way, and a lot of trial and error.
It will take a lot of thought, time and experimentation before chocolate makers figure out how to make great chocolate sweetened only with stevia, but I’m guessing it can be done. I’m curious which chocolate maker will be the first to make that leap.
Last week I wrote about the history of the awesome Italian chocolate-hazelnut confection called gianduja. In the following series of posts I’ll cover how gianduja is made (and how to make it at home), where to buy it, and what to do with it. I’m also really excited to share a couple of great gianduja recipes I’ve been working on.
We’ve already covered how traditional gianduja was made by combining chocolate and hazelnut paste to form solid, single-serving confections. However, in the 1940’s, 30 years after gianduja’s introduction to the world, soft gianduja spreads (called paste gianduja) started becoming popular in northern Italy as well. While you may not have heard of its firmer, foil-wrapped cousin, I’m betting most of you are probably quite familiar with Nutella.
Wait, so solid bars of gianduja and soft chocolate hazelnut spreads are actually the same thing?
Yes. The consistency of giandjua is the direct result of its ratio of chocolate to ground hazelnuts. Since cocoa butter is solid at room temperature but nut butters are quite soft, a firmer gianduja will have relatively more chocolate, where as a soft gianduja will be heavier on the hazelnut paste. So, for example, a solid bar of gianduja might have a 70:30 chocolate-to-hazelnut ratio, where as a creamy, spreadable paste will be closer to 50:50, or even 40:60.
Yum. Can I make spreadable gianduja at home?
Making fantastic gianduja spreads at home is simple and will spoil you forever — you’ll never buy that nasty imitation stuff again (I’m talking to you, Nutella). I have a fantastic recipe for homemade gianduja spread that I’m excited to share with you next week. All you need are roasted hazelnuts, melted chocolate and a food processor.
If homemade gianduja is just nuts and dark chocolate, does that mean it’s… HEALTHY?
My opinion? Yes, homemade gianduja spread is healthy (yeah I know… as if you needed another reason to eat more of it). It’s full of antioxidants, healthy fats, protein, fiber, vitamin B6, iron, magnesium, theobromine…. you get the picture.
What’s especially cool about making gianduja at home is that you can make a wildly potent, intensely flavored chocolate hazelnut spread with about 70% less sugar than most store-bought spreads. Nutella contains a shocking 57% processed sugar by weight (yikes), where as my recipe for homemade gianduja spread contains less than 16% sugar. Even better, my recipe doesn’t contain processed palm oil or any of the other cheap bulking agents found in most industrially produced chocolate hazelnut spreads.
How long will my homemade chocolate hazelnut spread last before it goes bad?
More good news. Due to the antimicrobial properties of chocolate and the long shelf life of nut butters generally, you can make a big batch of gianduja spread and store it in the fridge for six months or longer.
Hint: are you the type that likes to get holiday gift shopping out of the way early? Fill 6 oz. mason jars with homemade gianduja months before the holidays… but good luck trying to resist eating it all before December!
What else can I do with homemade gianduja besides, you know, eat it with a spoon?
So here’s a little teaser… homemade gianduja also makes for a fantastic truffle filling, and gianduja truffles have a much longer shelf life than ganache-filled truffles (always a bonus for chocolatiers). Keep an eye out for my recipe for these insanely addictive homemade Baci, coming soon.
Yes, these chocolates are every bit as dangerous as they look.
Before Nutella was a household name, and way before Perugina’s Baci were widely available in the U.S., Italians had gianduja.
I had my first bite of gianduja (“jon-doo-yah”) seventeen years ago, and to this day almost nothing makes me happier than this creamy chocolate-hazelnut confection.
Gianduja ranks right up there with pesto as one of the many mind-blowingly delicious culinary inventions gifted to the world by Italy. And like pesto, gianduja is pretty easy to make. It’s really just chocolate and hazelnuts. But something transformative happens when these two ingredients are ground together, something almost alchemical.
I was thinking about this recently… Who was the original gianduja alchemist? Who woke up one morning and thought, “Today would be a good day to toss a bucket of hazelnuts into the grinder with my cocoa nibs — YOLO.”
So, chocolate nerd that I am, I decided to find out. My research led me all the way back to the Napoleonic era, to the Great Cocoa Bean Shortage of 1840 (I’m making that up. But there really was a cocoa bean shortage, and it did happen in the early 1800’s, and it could have had a scary name).
A predecessor to gianduja was invented in the Piedmont region of northern Italy. During Napoleon’s occupation of that area, a British naval blockade obstructed cocoa bean imports from reaching coastal towns in northern Italy, so the price of cocoa beans skyrocketed. To maximize their limited supply, Piedmontese chocolate makers began diluting their cocoa beans with ground hazelnuts, which grew locally and were much cheaper. The new combo product turned out to be a big hit.
But it still didn’t have name.
Then in 1865, Turinese chocolate manufacturer Caffarel came out with Gianduiotto, a creamy chocolate-hazelnut confection that the company still makes today. Gianduiotto got its name from its shape — it’s supposed to resemble the hat of a Turin Carnival marionette named Gianduja. Gianduiotto was very popular with the locals, and the name stuck.
To this day, traditional Piedmontese chocolate makers like Venchi and Novi consider gianduja to be one of the four classic styles of chocolate (the other three being dark, milk and white).
According to a 2004 study in the UK, the amount of theobromine in a typical 2.5 oz dark chocolate bar works better than codeine to suppress the vagus nerve activity that triggers coughing.
In the study, participants were able to ingest significantly more capsaicin (the chemical that gives spicy chilies their kick) before coughing after they had taken 1,000 mg theobromine, when compared to those given a placebo.
Theobromine is one of the nervous system stimulants in chocolate. It dilates blood vessels, reduces blood pressure, increases heart rate and has a mild diuretic effect on humans*.
And apparently it’s also a cough suppressant! Sweet.
