One of the great things about this macaroni and cheese recipe is that it's so easy to remember; make it once and you'll have no problem making it again without a recipe in front of you. Almost everything is measured in twos: 2 cups macaroni, 2 cups cheese, 2 cups milk, and 2 tablespoons flour and butter. The result is a cheesy, rich mac and cheese that kids and adults will love. Using heavy cream makes this macaroni and cheese incredibly creamy and delicious, but it's still pretty great if you use whole or 2% milk. If you like, add more flavor to the noodles by throwing in a handful of diced ham or prosciutto, peas, or broccoli. You can also use a blend of cheeses instead of just cheddar. Some cheeses to try are gruyere, manchego, fontina, and cantal.
