Béchamel is a basic white sauce and one of the five mother sauces of classical cuisine. That means it's the starting point for making other sauces, like the cheddar cheese sauce, the mornay sauce, cheesy sauce, and several other variations. You can also season it and serve it as is. Or try making it with bacon or sausage fat for an amazing white gravy
