This recipe combines the soft and pillowy texture of gnocchi with the natural sweetness of sweet potatoes. The dish is topped with crunchy hazelnuts, adding a nutty flavor and a delightful crunch. The gnocchi are made from scratch using a combination of mashed sweet potatoes, flour, and eggs. They are then boiled until they float to the surface, indicating they are cooked. The gnocchi are then sautéed in butter until golden brown. The dish is finished with a sprinkle of toasted hazelnuts for added texture and flavor.
