I scoured the Internet looking for a recipe but only came up with some German sites that mentioned sherry potatoes, but no recipe. We have, however, finally arrived at a method that works, and recreates the divine potatoes we enjoy so much at the cafe. It’s very simple, baking sliced potatoes in butter and dry sherry, salting generously, and sprinkling on a little parsley. The dry sherry truly enhances the flavor of the butter. Remove from oven, sprinkle with chopped fresh parsley to serve.
