RecipeSource: Bechamel Sauce

There's the base for your cheese sauce. It's a simple bechamel. When you cook the flour, be very careful not to scorch it, or your sauce will taste a little off.

At the step where you add the milk, you can then add some shredded cheese of your choice (aqdd more milk if it seems a bit thick).

This is how my mother always made her mac-n-cheez. Bits of chopped ham and broccoli are great with it, or garlic, parmesan, and proscuitto with a touch of nutmeg.
