Ferran Adrià, named one of the best chefs in the world by the European Restaurant Ranking, is the mastermind behind "èspesso"—a solid espresso. Èspesso reportedly maintains the full flavor and aroma of regular coffee, while delivering a foamy consistency, similar to mousse. It sprays out of a can, like whipped cream; you serve it on a plate and eat it with a spoon. Èspesso is available in three flavors: cappuccino, macchiato, and of course, espresso.

Adrià's culinary exploits have been associated with molecular gastronomy. In addition to èspesso, he is responsible for creating foamed mushroom and meats, as well as liquid ravioli and frozen Parmesan air.
