Bring water to a boil and pull the pan off the stove. Put the macaroni in the water and put the lid on. Stick in in the Wonder Whatever and put the top on. Let it sit for 10 minutes.
Grease a Corningware pot.
Mix 6 eggs, 4 cups cheese and 1 cup milk in a mixing bowl. You can also add some chopped scallions, chopped bacon or other things you like in macaroni and cheese.
Drain the macaroni and pour it into the Corningware pot. Pour the egg/cheese/milk mixture over it. Put the lid on. Put it in a pot. Add enough water to the pot around the Corningware to come up about 2/3 of the side. Bring the water in the pot to a boil on the stove for 15 minutes. Set it in the wonder whatever and put the top on. Leave it for about an hour.
I used a pound of macaroni in a 2 1/2 quart corningware and a dutch oven.
