Pommes Anna

Pommes Anna, or Anna potatoes, is a classic French dish of sliced, layered potatoes cooked in a very large amount of melted butter. The recipe calls for firm-fleshed potatoes and butter only. Potatoes are peeled and sliced very thin. The slices, salted and peppered, are layered into a pan , generously doused with clarified butter, and baked until they form a cake. Then the cake is flipped every ten minutes until the outside is golden and crisp. At the end of the cooking period, the dish is unmoulded and forms a cake 15 to 20 centimetres (6 to 8 in) in diameter and about five centimetres (2 in) high. It is then cut in wedges and served immediately on a hot plate, usually accompanying roasted meats. A special double baking dish made of copper called la cocotte à pommes Anna is still manufactured in France for the cooking of this dish. It consists of upper and lower halves which fit into each other so that the whole vessel with its contents can be inverted during cooking.
