Aquafaba is the liquid found in tins of chickpeas, butter beans, kidney beans and any other bean. It acts a lot like egg whites, you can whip it up to create an airy structure in the batter. This is the exact reason we use it in our vegan Yorkshire pudding recipe – it also helps the batter rise.u003cbr/u003eu003cbr/u003eA great way of getting aquafaba is to buy dried beans and cook them yourself in boiling water. Remember: aquafaba is the water that beans are cooked in – that includes the water you cook them in at home! Buying them dried (and in bulk) is the cheapest way to buy beans, and uses less packaging too.u003cbr/u003eu003cbr/u003eIt’s also great for making vegan meringues, marshmallows, chocolate mousse, fudge, ice cream and even hummus or quiche!
