Aquafaba is a thickened water in which legume seeds such as chickpeas are cooked. Aquafaba is used as a substitute for
eggs and egg whites. Its composition of carbohydrates, proteins and other soluble plant solids that pass from the seeds to the water during cooking gives it a wide range of emulsifying, foaming, binding, gelatinizing and thickening properties. It is particularly popular in vegetarian and vegan recipes.
