A pâtissier is a professional pastry chef who specializes in creating a variety of sweet baked goods, such as cakes, pastries, and desserts. They often work in bakeries, restaurants, or hotels, where they use their skills to prepare and decorate items like croissants, tarts, and mousses. In addition to baking, a pâtissier must have a good understanding of flavors, textures, and presentation. They often collaborate with other kitchen staff, including chefs and bakers, to create a cohesive menu. Training typically involves formal education or apprenticeships to master the techniques of pastry making.
