My totally retro, 50s-style, heart-attack-on-a-plate recipe for homemade macaroni and cheese. Always a big hit at a potluck:
1 lb. macaroni
½ cup butter
½ cup flour
1 teaspoon salt
freshly ground pepper, to taste
4 cups milk (preferably whole milk [we're not really working a health food angle here

])
6 cups good, sharp grated cheddar cheese
2 teaspoons mustard powder
3-4 slices white sandwich bread
½ cup freshly grated parmesan cheese
2 tablespoons butter
Preheat oven to 375. Grease a 9 by 13 pan.
Process bread slices in food processor to make bread crumbs. Place in small bowl.
Add grated parmesan and mix.
Cook macaroni for 5-6 minutes. Drain.
Meanwhile, make sauce. In a large pot, melt 1/2 cup butter over low heat. Add flour and
mix. Add salt and pepper. Cook over low heat for a minute or two. Add milk and
mustard powder and stir well. Cook over medium heat, stirring constantly with a
whisk, until smooth and thickened. Remove from heat, add cheese and stir well to
melt cheese.
Add drained macaroni to cheese sauce and fold in. Pour into prepared pan.
Melt 2 tablespoons butter and stir into bread crumb-parmesan mixture. Top the macaroni
with the buttery bread crumb-parmesan mixture.
Bake, covered, for 15-20 minutes. Remove cover and bake uncovered, for another 10-15 minutes or so, until the bread crumb mixture is nicely browned.
