I took a vegetarian cooking class recently and the demonstrator mention aquafaba. I had no idea what she was talking about so figured, I would Google it later. Well, I learned something new today, aquafaba is the liquid from a can of beans.
I also learned that if you are vegan or working towards becoming a vegan, you can use this liquid as an egg replacement. For recipes where eggs are needed to bind or add moisture like in cookies and cakes, using 3 tablespoons of aquafaba can replace 1 egg and liquid from chickpeas and white beans usually works best due to its neutral color.
So, just a little tidbit of information for those working their way to becoming a vegan.
