Tarte Tatin is a super-easy, very fast cake with caramelized apples, and it tastes awesome. It may look a bit sturdy, but who cares?
The story behind this cake is that the sisters Calorine and Stéphanie Tatin, who ran a famous inn in a little town in central France once forgot to make desert, because they were chatting with a guest. By the time Stephanie realized her mistake, there was very little time left to serve the desert. So she tossed in the oven some peeled apples with butter and sugar, and while they were being baked, she made some dough. As the dough was prepared after the apples, she had no choice but to cover the apples with the dough. When it was ready, she realized that it can be served upside-down, so that the apples are on the upper side.
