Recipes and techniques generally advance in baby steps. It’s rare that you find a technique so far out of left field that it changes the way people think about food overnight. Sous vide cooking is up there, as is no-knead bread. In the world of vegan cuisine, nothing has shaken things up like aquafaba—the recently coined term for the liquid inside a can of cooked beans. It’s the kind of technique that’s so mind-blowingly simple that I’m amazed nobody discovered it until just a couple of years ago.
I discovered aquafaba with a recipe for two ingredient meringues a few months ago. It has since nearly completely replaced my use of prepackaged egg substitutes. I am eating a lot more chickpeas now as a result. I’ve also found that canned chickpeas freeze well and defrost quickly.
