A French upside–down apple tart of recent invention named after the two French sisters who first served it in their restaurant. The French give it the name of la tarte des demoiselles Tatin, meaning ‘the tart of the two unmarried women named Tatin’. The sliced apples are caramelized in sugar and butter in a shallow baking dish. A pastry case completely covers the top, it is baked, then turned upside down to show the apple and juices. Tarte Tatin is now also made with pears, pineapple, mango or even vegetables such as shallots.
