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
