Baked Macaroni & Cheese

16 ounces cooked macaroni
4 tablespoons butter
4 tablespoons flour
1 cup milk
1 cup cream (or evaporated milk)
1/2 teaspoon salt
fresh ground black pepper, to taste
2 cups cheddar cheese, shredded good quality
1/2 cup breadcrumbs, buttered

Preheat oven to 400°F. Cook and drain macaroni according to package directions; set aside. In a large saucepan melt butter. Add flour mixed with salt and pepper, using a whisk to stir until well blended. Pour milk and cream in gradually; stirring constantly. Bring to boiling point and boil 2 minutes (stirring constantly). Reduce heat and cook (stirring constantly) 10 minutes. Add shredded cheddar little by little and simmer an additional 5 minutes, or until cheese melts. Turn off flame. Add macaroni to the saucepan and toss to coat with the cheese sauce. Transfer macaroni to a buttered baking dish. Sprinkle with breadcrumbs.
Bake 20 minutes until the top is golden brown.
