Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lump crabmeat
- Forms the main body of the dish and provides its seafood flavor.
- Butter
- Enriches the sauce and carries flavor as the base for the roux.
- Flour
- Thickens the butter and milk into a smooth, stable sauce.
- Milk
- Liquid that hydrates the flour and forms the body of the sauce.
- Processed cheese
- Melts into the sauce and browns on top for richness and color.
The step that matters
Adding milk to the roux. Adding milk over low heat and stirring steadily lets the starch in the flour swell evenly. Heating too fast or stopping stirring can leave lumps or a sauce that does not thicken smoothly.
Swap the onion
How well each one fits the dish's main ingredients (butter, flour, milk, cheese, pepper, sauce):
- Capsicumfits better
- Potatofits better
- Mustardfits better
- Onionthe original
Fit is the average pairing score against butter, flour, milk, cheese, pepper, sauce. Candidates are from the same food group and used in at least 100 recipes.
