1/2 cup butter or margarine
10 slices white bread cut into 1-inch cubes
3 cups shredded Cheddar cheese
2 cups milk
3 eggs, separated
1/2 teaspoon salt
1/2 teaspoon dry mustard
1/2 teaspoon red pepper
Melt butter; add bread cubes, stirring until coated. Add cheese and stir well. Combine milk, egg yolks, salt, mustard, and pepper; beat well. Pour over bread cubes. Beat egg whites (at room temperature) until stiff but not dry; fold into the bread mixture. Spoon into a lightly greased 12x8x2-inch baking dish. Cover and chill overnight. Bake, uncovered, at 325 degrees F. for 30 minutes or until set.
