If you're looking for a twist on the classic potato gnocchi, try making sweet potato gnocchi. The sweet potatoes add a subtle sweetness and a beautiful orange color to the dish. Boil the sweet potatoes until tender, mash them, and mix in flour, egg, and a pinch of nutmeg. Roll the dough into long ropes, cut them into small pieces, and shape them into gnocchi. Boil them until they float to the surface, then serve with a brown butter sage sauce or a creamy gorgonzola sauce.
