A while back, I tried unsuccessfully to create chocolate mousse out of whipped chickpea canning liquid (aka aquafaba). I had such high hopes. But alas, after several failures in a row, I threw in the towel.

At the time I was making a lot of hummus and chickpea blondies (yes, they’re a thing), and I didn’t want to throw away all that (potentially) useful chickpea canning liquid. So… I saved it. Lots of it. And I tried again. This time, it worked.

What made the difference? I’ll share some tips further down in the post. But first, the recipe:

Recipe:

• liquid drained from 15 oz can of chickpeas
• 1/4 cup confectionery sugar
• 1/4 tsp cream of tartar
• 1 tsp vanilla extract
• pinch of salt
• optional: 1 tbsp cocoa powder (the dutch processed kind, if possible)

Directions:

Throw all ingredients except the optional cocoa powder in a bowl and whip with electric beaters on high for 6-12 minutes. Add the optional cocoa powder at the end, and be careful not to over beat it.

That’s it.

Tips & Suggestions:

• Chill the liquid before you attempt to whip it.
• Use the highest setting on your electric egg beaters. If you own powerful electric beaters, you should have stiff peaks in 6-7 minutes (if your electric beaters aren’t so powerful, this may take you 10+ minutes, but it will work… eventually).
• Use real sugar. Liquid sugars like honey and agave might also work, although I haven’t tried them so I can’t say for sure. But don’t use stevia — it tastes awful in this recipe. Trust me on this one — this is chickpea liquid we’re talking about, it already has a weird aftertaste and stevia seems to accentuate it.
• Flavor with vanilla extract, even if you’re making chocolate mousse. Vanilla masks the chickpea flavor quite well.
• Don’t try to bake these. While I know numerous vegan bloggers (and the New York Times) have claimed that these can be baked into meringues, I’ve tried several times with no luck. I’m pretty much convinced it’s impossible. The “meringues” will melt into puddles after just a few minutes in the oven. Low heat, high heat — it doesn’t seem to matter, they deflate into sad little puddles. Then they burn. They smoke. They stink up your whole house. Your husband will shake his head in bemused resignation as he disables the smoke detector (again). Skip the meringues.

 

• If adding cocoa powder:
  • Add the cocoa at the very end, after you’ve already whipped up a nice mousse. Also, since the cocoa powder will devolumize your mousse, you’ll need to eat this immediately.
  • To prevent over-mixing/deflation (see pics below), make a cocoa paste by adding a little chickpea liquid to the cocoa powder and stirring until smooth. Then FOLD the paste into the mousse using a spatula or wooden spoon. Don’t use electric beaters to do the mixing — you’ll deflate your mousse.
  • Use dutch processed cocoa powder, which is less acidic and dissolves more easily than the natural (undutched) type. Use only the bare minimum amount necessary to develop chocolate flavor (~1 tbsp for this recipe, give or take).
  • Try this recipe with real dark chocolate rather than cocoa powder. Melt the chocolate gently in the microwave (you can follow these instructions) and gently fold it into the whipped chick pea liquid. Then chill the mousse for a couple of hours to give the cocoa butter in the melted chocolate time to harden. The resulting mousse will be much longer lasting (and tastier) than the cocoa powder version. Just my $0.02.

My personal feelings about aquafaba mousse? If you’re a vegan and have a killer craving for chocolate mousse, this recipe is for you. Otherwise… my honest opinion is that egg whites are a better foundation for a mousse. Even when pasteurized, egg whites whip faster, plus they hold their shape better when baked.
