Which fruit is typically used in a traditional tarte Tatin?

Tarte Tatin is a classic French dessert known for its unique method of preparation, where fruit is caramelized in butter and sugar before being covered with dough and baked upside down. Apples are the traditional choice for this dessert due to their ability to hold their shape and provide a balance of sweetness and tartness when cooked. Varieties such as Granny Smith or Golden Delicious work exceptionally well, as they caramelize nicely and maintain their texture throughout the cooking process.

While pears, cherries, and peaches could technically be used in other tart recipes or variations of a tart, they do not embody the classic essence of a tarte Tatin. The use of apples is so distinct that when one thinks of a traditional tarte Tatin, apples are the fruit that comes to mind, making them the quintessential choice for this delightful dish.
