Not only is this dessert delicious, it was invented quite near where I was staying by the Tatin sisters. The story goes that one of them was making an apple tart but, for whatever reason, made a mistake and left it too long in the oven. However, she thought she could salvage it, so she ended up turning it upside down and her guests went mad for it. I wish all my cooking mistakes had such happy results. Hopefully, this recipe will give you the basics so that you'll be able to stretch it by using pears, quinces, peaches, apricots or a mixture... I'm sure the sisters would love the fact that people were bending this recipe to make it their own. Light golden puff pastry, soft juicy fruit and crisp caramel is a great combination! You could serve this with a spoonful of creme fraiche or whipped cream, but personally I love the contrast between the warm tart and cold ice cream, especially the prune and Armagnac ice cream!
