A classic in brasseries and restaurants, Tarte Tatin is a caramelized apple tart made with sugar and butter, with the pastry placed on top of the filling. After baking in the oven, it is flipped onto a plate and served warm with a little fresh or whipped cream. Its accidental discovery by the Tatin sisters is a story invented by the food critic Curnonsky, who popularized this dessert in Paris in 1926.
