Tool: Pommes Anna Pan
Pommes Anna is the classic French dish of sliced and layered potatoes cooked in a very large amount of melted butter. It was created by Chef Adolfe Duglere in the 19th century in honor of actress Anna Deslions.
The pan is a special double baking dish made of copper consisting of upper and lower halves which fit into each other so that the whole vessel with its contents can be inverted during cooking. At the end of the cooking period, the dish is unmolded and forms a cake 6 to 8 inches in diameter and about 2 inches high.
