-Change up the recipe by adding caramelized onions, sautéed mushrooms or spinach, or steamed cauliflower.
-This recipe makes a generous amount of sauce--the more, the better!
-It's best to mix the sauce into the pasta right before serving. If it sits, it will get a little thicker. You can fix this by stirring in a little hot water and a pinch of salt.
-Since most fresh fettuccine pasta is made with eggs, you'll want to use dried fettuccine, which is most often made with just wheat and water. Just check the ingredients to be sure.
-Make this sauce gluten-free by replacing the flour with the same amount of cornstarch or tapioca starch. Then combine it with your favorite gluten-free pasta.
