Last weekend I spent Sunday afternoon holed up at Union Kitchen with a professional chocolate maker and a former chocolatier*.
The mission: make chocolate truffles out of Undone Chocolate.
The plan: make a ganache out of Undone’s salted 72% chocolate bars, pour into a frame and let it cool in the industrial refrigerator, then cut it into squares and dip it in tempered Undone Chocolate.
The twist: decorate the truffles with chocolate transfer sheets.
Chocolate transfer sheets are like temporary tattoos for truffles: you press them on when the chocolate is in liquid form, and when the chocolate hardens and you peel them off and the pattern of the colored cocoa butter remains on the surface of the truffle as if you’ve used a stencil and spray paint. (Non-toxic spray paint, naturally).
Transfer sheets can also be used with specialty molds. We actually did consider using molds for these truffles but quickly realized it was unworkable — the chocolate was simply too thick for small molds and wouldn’t spread evenly into the corners.
Why is Undone Chocolate so thick? Well, that’s just what happens when you make two-ingredient chocolate. Most chocolate makers add additional cocoa butter to the other ingredients (primarily cocoa mass and sugar) before grinding and refining them. Undone skips this step. The resulting chocolate is potent, thick and intense, and it won’t easily spread into the crevices of molds (this is also a characteristic of “high viscosity” chocolate).
Anyway… we opted for hand dipping the ganache squares in chocolate, and we added some additional cocoa butter to it to make the enrobing process easier. This turned out to be a good call. The extra cocoa butter produced a couverture-like chocolate that tempered well and left our bonbons with nice thin shells.
I cut the transfer sheets into squares and pressed one onto each enrobed truffle while the chocolate shell was still wet. Chocolatiers with fancy equipment skip this part — they can cut the entire slab of ganache at once using a guitar cutter**, after which they send the pre-cut ganache squares through an enrobing machine (it’s like a chocolate shower) hooked up to their tempering machine.
In any event, the transfer sheets worked beautifully. I recommend them to home chocolatiers attempting to create professional-looking truffles without colored cocoa butter or fancy molds. I bought these particular transfer sheets from Chef Rubber, but you can buy small quantities of them cheaply on Amazon.
*Chocolate makers are the people that roast raw cocoa beans and grind them into chocolate. Chocolatiers take a chocolate maker’s product and turn it into confections, like truffles.
**Btw… that guitar cutter is a $2000 piece of equipment. And tempering machines with enrobing attachments can cost ten times that. Of all the barriers to entry faced by aspiring chocolatiers, the initial capital investment in equipment is probably the most difficult to surmount. But I digress.
