Aquafaba is strange and miraculous.
Aquafaba vegan chocolate mousse – version 1
Aquafaba, the equivalent of four egg whites
1 cup sugar
Several tablespoons of sifted unsweetened cocoa
(You could also add vanilla extract and/or vanilla bean powder when you’re adding the cocoa. You can also add a lot more cocoa if you prefer. I used about two tablespoons, so it has a light chocolate touch.
Heat sugar and aquafaba, whisking together, in a glass bowl over a saucepan filled with water, gently simmering.
When the sugar is completely dissolved, transfer the mixture to a mixing bowl of a stand mixer. Use the whisk attachment to whisk at high speed until it comes together in medium peaks.

Can you believe that this is chickpea water?!
Sift cocoa in and this point and continue to whisk – this will take while but will become fluffy eventually.
Put in individual serving bowls and refrigerate for a few hours.
It’s not ‘pretty’, and this won’t be quite like the mousse you might be used to. It is very light but has a chocolatey marshmallow flavor.
This is a very simple version of a kind of vegan “mousse” you could make if you want something chocolate, light, easy, and vegan. I will soon try another version.
