Jordi Roca runs a three Michelin-starred restaurant, El Celler de Can Roca, in Girona near Barcelona, Spain.

It has been on the list of the world's 50 best restaurants for the past seven years and it was recently voted number two in the world for the second year in a row.

He is the pastry chef at the restaurant, which he runs with his two older brothers, and he has a reputation for creating some of the most innovative and artistic desserts to be found on menus anywhere in the world.

Roca is particularly famous for creating a range of spectacular puddings based on perfumes, such as Calvin Klein's Eternity and Dior's Poison, using flowers, sugar sculpture and hi-tech cooking methods.

He also runs an ice cream parlour nearby, serving up delicious sweets with candy floss and rose petals, creating the stuff of childhood dreams.
