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

What each ingredient does

Eggs
Hard-cooked slices add protein-rich body and a firm, sliceable layer in the casserole.
Cornstarch
Thickens the milk sauce as it heats, giving it a smooth, spoonable texture.
Cheddar cheese
Melts into the sauce, adding richness, savory flavor and a creamy texture.
Potatoes
Cooked cubes provide starchy bulk and a soft, tender texture in the baked dish.
Skim milk
Forms the base of the sauce, providing liquid that thickens with cornstarch.
Dijon-style mustard
Adds sharp, tangy flavor that balances the richness of the cheese and milk.

The step that matters

Thickening the sauce. Cornstarch must be cooked with the milk until it thickens and bubbles; otherwise the sauce stays thin and tastes starchy. Stirring keeps it smooth and prevents lumps from forming.

Swap the mustard
