For the past year or so, I've been hearing a lot about aquafaba, the protein-rich liquid found inside a can of chickpeas. It's pretty amazing stuff—you can whip it into stiff peaks like a meringue, use it to leaven pancakes and waffles, or make light sponge cakes, all without any eggs at all. You can also use it to make mayonnaise. Or so they say.
NYT Cooking: This recipe is adapted from one by Sir Kensington's, the condiment company in New York that uses chickpea liquid, or aquafaba, to make its vegan mayonnaise. Vegans have embraced the liquid, which whips up instantly into peaks and froths and retains none of its bean-like flavors, and works perfectly as a leavener and as a base for delicious homemade mayo.
