Heat the milk and cream together to a boil. Melt butter in saucepan. When melted, then add all the flour stirring constantly. Let cook for 4-5 minutes, continuing to stir. Remove from heat and add warm milk and cream while whisking if sauce is too thick, add a touch more milk.

Add cheese to white sauce and stir. (Save a bit of cheese for the topping. I also add bread crumbs and paprika to the top). Stir sauce into macaroni and place in a buttered casserole dish. Place in 350° oven until slightly brown and bubbly on top 25-30 minutes.
