Aquafaba is a starchy liquid that you find in a can of chickpeas or after cooking chickpeas on your stovetop. In fact, aquafaba can be made with most legumes but chickpea aquafaba is most common. It can be used as an egg alternative in many vegan recipes with approximately 1/2 cup aquafaba equalling 2 eggs. Whipping aquafaba can make an eggless meringue which is why adding aquafaba to your hummus can make it oh so creamy and just a little bit fluffy.
