Today’s macaroons are easy and fun little treats using just a few store-cupboard ingredients. Whenever I use a can of beans (which, frankly, is most days), I try to include the aquafaba, or bean water, in whatever it is I’m making. Inevitably, though, I sometimes end up with a bit left over, which means I have to get creative to find a way to use it up. Sometimes, I’ll include the liquid in a soup or stew, or use it to make mayonnaise, caesar salad dressing or a whisky sour. When my sweet tooth kicks in, or when I want to bake with my daughter, however, I often use it to make a simple sweet snack such as today’s macaroons. Using aquafaba in baking saves money, too. Good eggs are expensive, so I’d rather save them for when they’re essential to a recipe.
