For such an extravagant name it is literally just the water that your pour out of a can of chickpeas… This starchy and yellowish liquid foams up just like egg whites, and is the common alternative used to make vegan meringues, and to create fluffy flour free cakes.
For all you chocolate orange lovers out there (I got you) it makes a simple addition to the recipe, but can also be subbed in for any of your favourite flavour combos. Just make sure you don’t add too much, and you fold super gently to maintain the cloud-like goodness.
