Pommes Duchesse, also known as Duchess potatoes, are basically some puréed potatoes that includ egg yolk, butter and seasonings. They can be simply shaped into a mound with a spoon or piped through a pastry bag into various shapes. The edges of the piped potatoes are crisp after baking, while the interior remains soft and creamy. Serve duchess potatoes as a side along with a good portion of meat.
