Potthucke is a traditional potato cake originating from the Sauerland region in Westphalia. It's made with a combination of potatoes, eggs, milk, sour cream, butter, salt, and pepper. Half of the potatoes are boiled and grated, and the remaining half is boiled and mashed.

The two are mixed together with sour cream, milk, eggs, seasonings, and the white starch from the cooking liquid. The batter is poured into a greased loaf pan, dotted with butter, and baked until browned and crisp. Once cooled, the loaf is typically cut into thin slices and sautéed in butter on both sides before it's served hot.

Potthucke is traditionally washed down with schnapps or beer. This savory cake has many variations, so it can also contain ingredients such as bacon and onions.
