Trailblazing pastry chef Yann Couvreur has a trio of shops in Paris and a string of books, including two for children, to his name. His organic pâtisserie, chocolate, and frozen desserts are guided by his commitment to true seasonality and respect for nature, whether it’s his apricot, almond, and lemon thyme tart, a slice of raisin bread, or his infamous vanilla mille-feuille. Although he is a master of classic French favorites, you won’t find any raspberries in his shops in winter, or artificial colorings or flavorings at any time of year. His strong ethics and sustainable approach have made him a success around the world, with openings in Seoul, Dubai, Miami, and a new pastry school in Paris.
