The humble chickpea, a staple in cuisines worldwide, has given us hummus, falafel, and countless other delicious dishes. But what about the liquid it’s cooked in? Often discarded, this seemingly insignificant byproduct, known as aquafaba, has revolutionized vegan cooking and captured the attention of food enthusiasts everywhere. Can you really eat chickpea water? The answer is a resounding yes, and the story behind it is far more fascinating than you might think.
What Exactly is Aquafaba?
Aquafaba, derived from the Latin words “aqua” (water) and “faba” (bean), is the viscous water left over after cooking legumes, most commonly chickpeas. This liquid is rich in starches and proteins, leached from the beans during the cooking process. These compounds are what give aquafaba its unique properties, allowing it to mimic the functionalities of egg whites in various recipes.
The Science Behind Aquafaba’s Magic
The magic of aquafaba lies in its ability to emulsify, foam, and bind ingredients. The starches contribute to its thickness and stability, while the proteins act as surfactants, reducing the surface tension between liquids and allowing them to mix together. This is the same principle that allows egg whites to create stable foams like meringue. When whipped, aquafaba traps air, forming a light and airy texture. This ability to mimic egg whites makes it a game-changer for vegan baking and cooking.
The Accidental Discovery of Aquafaba
The story of aquafaba’s discovery is a testament to culinary curiosity and resourcefulness.
