*Easy Cheese Sauce: In a small, heavy saucepan, melt 1 tablespoon butter. Whisk in 1 tablespoon flour until smooth. Add a pinch each: kosher salt, fresh ground black pepper, cayenne, and dry mustard or nutmeg. Let cook two minutes, stirring, and then whisk in 1 cup barely warm milk. Bring to a simmer, stirring, and cook until sauce begins to thicken. Stir in 1/2 cup grated sharp cheddar until smooth. Taste and adjust seasonings. (If you like thicker sauce, you can whisk together a little more flour in a 1/4 cup of flour and stir it in before adding the cheese… or just begin with double butter and flour to start with. The traditional flavorings here are onion and nutmeg. If you’d like to use onion, mince a teaspoon and cook it in the butter before adding the flour and making the roux.)
