The main ingredient in gnocchi is potato. These Italian dumplings are typically made from a mixture of cooked potatoes, flour, and sometimes egg, creating a soft and pillowy texture. Potato gnocchi are a beloved staple in Italian cuisine, often served with a variety of sauces, from simple butter and sage to hearty tomato sauces. While potatoes are the primary ingredient, variations can include ricotta or other types of flour, depending on regional preferences and recipes.
