Tortelli alla lastra

Tortelli alla lastra is a traditional dish hailing from Tuscany. These tortelli are similar to ravioli, and the dough is made with flour, water, and salt. Once prepared, it's rolled and cut into thin and large rectangles or squares. The tortelli are then stuffed, usually with a combination of pancetta, mashed potatoes, eggs, wild greens, ricotta, pumpkin, and seasonings, with every ingredient used depending on its availability. Each stuffed tortello is cooked on a slab or a tile which was originally made of clay, but nowadays it's made of cast iron. The slab was placed over the embers in the fireplace, but today cooks often use the top of the stove. They're often served with a sauce consisting of tomatoes, garlic, sage, celery, carrots, and onions, although all of the ingredients for the sauce can also be used in the filling. The dish can be eaten hot or cold, and it's recommended to follow it up with a glass of wine.
