Smoked Cheddar Sauce on Everything

I make this cheese sauce in a big batch because it keeps in the fridge for at least a week. Using gluten free flour to thicken makes this recipe more versatile...great on warm bread but also tossed with steamed vegetables, poured over corn chips or used as a dip.

8 tablespoons butter

1/2 cup flour or gluten free

4 cups warm milk

16 ounces grated smoked cheddar cheese
