Sweet dishes served as a last course are called "desserts". Desserts are usually eaten at the end of a meal, after the main course has been served. They are typically sweet in taste and can be served in many different forms, such as cakes, pies, puddings, ice cream, fruit, or pastries. The purpose of serving desserts is to satisfy the sweet tooth and provide a satisfying end to a meal. Appetizers are served at the beginning of a meal to stimulate the appetite, entrees are the main course of a meal, and savouries are usually salty or spicy dishes that are served as a snack or as part of a meal.
