Ravioli is a popular type of pasta that consists of a filling enclosed in a thin pasta dough. Three-cheese ravioli, as the name suggests, typically contains a filling made from a combination of three different types of cheeses. While the specific cheeses used can vary, here's a general description of what you might find in three-cheese ravioli: Ricotta, Parmesan, Mozzarella. The combination of these three cheeses creates a filling that is creamy, savory, and rich in cheese flavor. Three-cheese ravioli can be served with a variety of sauces, such as marinara, Alfredo, or brown butter and sage, to complement and enhance the flavors of the pasta. It's a popular choice in Italian cuisine and is enjoyed by many for its comforting and indulgent taste.
