Albert Adrià Acosta is a Spanish chef whose work centers on avant-garde cuisine and pastry, developed over many years as head pastry chef at El Bulli, the influential restaurant located in Roses on the Costa Brava. He has worked closely with his brother Ferran Adrià, contributing to the experimental culinary approach for which El Bulli became internationally recognized. Adrià subsequently became head chef of Enigma, a two-Michelin-star restaurant in Barcelona. His 2008 book *Natura* reflects his engagement with natural forms and visual aesthetics in pastry and dessert work, characteristic of the boundary-pushing philosophy he honed during his time at El Bulli.
