2 cups milk
6 slices American cheese
When the sauce is ready, it goes over a pound of pasta.
Double, triple as needed.
This is what I grew up with except we used munster, or mozzarella, or colby-jack, or mild cheddar (the key is: WAY more cheese than you think; six slices seems on the low end/too little). You can turn it into baked by throwing an egg or two into the the sauce and sticking it in the oven for an hour or so. If you're serving grown-ups, add plenty of paprika, garlic, pepper, and mustard to the sauce but for a proper kid-pleaser bland is the way to go.
