Armstrong's Cheese Sauce Ingredients: 2 Tbsp. Butter 2 Tbsp. Flour 1 1/4 C. Milk (I like to use a mixture of half and half and milk), heated Salt 1/2 C. Cheddar Cheese Preparation: Melt the butter in a saucepan. Stir in the flour and cook, stirring constantly, until the paste cooks and bubbles a bit, but do not let it brown, if it browns start over again. This will take a couple of minutes. Add the hot milk, stir continually, and the sauce will begin to thicken. Bring to a small boil and cheese, and salt to taste. Add a dash of Cayenne and paprika.
