Cheese and Asparagus Casserole

Preheat oven to 400 degrees. Drain asparagus cooking water into a quart measure and add enough light cream to measure 3 cups. Melt 4 tablespoons butter over moderate heat and blend in flour. Add the 3 cups liquid and heat, stirring constantly, until thickened. Add salt, pepper, and 1 cup cheese; cook and stir until cheese is melted. Arrange asparagus in buttered shallow 2 quart casserole and top with cheese sauce. Toss remaining cheese with bread crumbs, sprinkle over sauce, and dot with remaining butter. Bake, uncovered, 10-12 minutes until bubbly and touched with brown.
