I found this recipe in a magazine. I love Kraft Macaroni and Cheese but sometimes you just need to make it from scratch.
Macaroni and Cheese
1 lb. dried macaroni
1 egg
4 tablespoons butter
1/4 cup all-purpose flour
2 1/2 cups whole milk
2 teaspoons mustard powder
4 3/4 cups grated Sharp cheddar cheese
1 teaspoon black pepper
1/2 teaspoon salt
1/2 teaspoon seasoned salt
Preheat oven to 350 degrees. Grease a 2-to-3 quart baking dish.
In a large pot of salted water cook macaroni for 4 minutes. Drain. Macaroni will still be firm.
Beat the egg in a bowl and set aside.
In a large saucepan, melt butter over medium-low heat and whisk in flour, stirring constantly, for 5 minutes. Whisk in the milk and mustard until smooth. Cook until very thick, stirring constantly for 5 minutes. Reduce heat to low. Slowly pour 1/4 cup of the sauce into the beaten egg, whisking constantly, to temper the egg. Pour egg mixture back into the sauce.
Reserve 1/2 cup of the cheese and stir the rest into the sauce until melted. Add the pepper and salts. Stir in the macaroni, then pour into the baking dish and top with reserved cheese.
Bake until bubbly and golden, 20 to 25 minutes.
Serves 8.
