Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs
Set the custard-like base, binding the macaroni and cheese into a sliceable casserole.
Milk
Provides the liquid that creates a creamy, saucy base around the pasta.
Cheddar or jack cheese
Melts into the sauce, adding richness, savory flavor and a creamy texture.
Macaroni
Forms the body of the casserole and absorbs the surrounding sauce as it bakes.
Bread crumbs
Toast in the oven, adding a golden, crisp topping that contrasts the soft interior.
Butter
Adds fat and richness, and helps the bread crumbs brown evenly on top.

The step that matters

Bake until the centre is set. Beaten eggs firm up as they heat, around 160°F, so the casserole needs enough time for the centre to set. Pulling it early leaves a loose, soupy middle.

Swap the mustard

How well each one fits the dish's main ingredients (butter, milk, cheese, egg, bread):
