In a small saucepan, melt the butter over low heat, blend in flour and cook about 2 minutes. Beat in the milk, then the cream and cook over medium heat, stirring constantly, until the mixture comes to the boil and thickens. Remove from heat. Stir in the cheese until melted, then the crushed tomatoes, sugar and two peppers. Stir in the macaroni. Pour into a shallow, buttered baking dish and bake in a preheated 400-degree oven until the surface browns, 25 to 30 minutes. Serves 2 or 3. NOTE: This recipe must have been broken down from one that made an enormous quantity, which explains the small amount of light cream. If you don't want to purchase a half-pint container of light cream just for two tablespoons, simply add two tablespoons more milk. You'll never know the difference. I also think it needs a little salt, which is not called for in the recipe.
