Espuma is a Spanish word that translates to "foam" in English. It refers to a light, frothy substance formed by the agitation of a liquid, often seen in beverages like beer or coffee. In culinary contexts, espuma can also describe a technique where ingredients are whipped to create a light, airy texture, enhancing the presentation and mouthfeel of dishes. In the world of gastronomy, espuma has gained popularity as a modernist cooking technique. Chefs use tools like siphons to create flavored foams, adding unique tastes and textures to their creations. This innovative approach has transformed traditional dishes, making them more visually appealing and exciting for diners.
