Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Forms the fat base that is cooked with the flour before the liquid is added.
- Flour
- Thickens the liquid into a smooth sauce once it is cooked with the butter and heated.
- Milk
- Adds liquid and richness, helping the sauce become creamy as it thickens.
- Hard-boiled eggs
- Add body and texture to the sauce as diced pieces stirred in at the end.
The step that matters
Adding the liquid gradually while stirring. Adding the haddock water and milk slowly while stirring continuously keeps the flour dispersed, which prevents lumps and gives a smooth, evenly thickened sauce.

Fit is the average pairing score against egg, butter, flour, haddock, milk. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
