Thin the mixture with hot milk and let it boil for 5 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Fat that combines with flour to form a roux, giving the sauce body and smooth richness.
- Flour
- Starch that thickens the melted butter and milk into a smooth, coating sauce.
- Milk
- Liquid that hydrates the flour starch and forms the body of the sauce.
- Cheese
- Melts into the sauce, adding flavor and a creamy, savory texture.
- Hard-cooked eggs
- Add chopped protein and body to the sauce, giving it texture and substance.
The step that matters
Thin the mixture with hot milk and let it boil for 5 minutes. Adding cold liquid too fast can make lumps as starch clumps before it disperses. Hot milk added gradually, then boiled, lets the flour starch swell fully and thicken the sauce smoothly.
Swap the mustard
How well each one fits the dish's main ingredients (butter, flour, pepper, milk, cheese, bread, egg):
- Capsicumfits better
- Potatofits better
- Asparagusfits better
- Mustardthe original
Fit is the average pairing score against butter, flour, pepper, milk, cheese, bread, egg. Candidates are from the same food group and used in at least 100 recipes.
