Open the can and pour it out through a strainer so as to separate the chickpeas from the liquid (
aquafaba). NOTE: Any aquafaba you don't use in this recipe can be saved by pouring it into ice cube trays until frozen. Once the cubes are frozen, pop them out, store it in a bag, and use anytime you need. Aquafaba is a great egg replacer, it can be used to make ice cream, mayonnaise, meringue, marshmallow fluff, and more.
