For an even richer flavor, consider using a combination of ricotta and mascarpone cheese in the filling. If you don't have a pasta machine, don't worry! Rolling the dough out by hand works perfectly well, just ensure it's thin enough. Agnolotti are delicious with a simple brown butter and sage sauce, a classic tomato sauce, or a creamy Alfredo. Freshly grated nutmeg adds a warm, aromatic note to the cheese filling. To prevent the agnolotti from sticking together while cooking, add a tablespoon of olive oil to the boiling water.
