Make your own homemade white sauce mix and store it in your pantry for sauces in an instant. This recipe is a great substitute for bottled Alfredo sauce, which can get expensive. The mix itself is just nonfat dry milk powder, flour, and salt, with butter cut in until the mixture is fine.

To make the sauce, you add cool water and heat it until thickened. To substitute for a 16-ounce jar of purchased Alfredo sauce, you should use 3/4 cup of the mix and 1-3/4 cups of water. Season it any way you'd like; it's delicious with added dried thyme, basil, tarragon, or marjoram. You can make this a cheese sauce by adding freshly grated cheese of any type: cheddar, Colby, Havarti, Parmesan, Romano, or Swiss.

This sauce is excellent in casseroles and can be used to make super-fast macaroni and cheese or scalloped potatoes. White sauce is a classic recipe and everyone should know how to make it. You can double this recipe if you use it a lot. Store in a tightly sealed container in the refrigerator up to 2 months.
