Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- String beans
- The main vegetable, cooked until tender and coated by the sauce.
- Cold milk
- Forms the liquid base of the cream sauce.
- Flour
- Thickens the milk into a cream as it cooks.
- Soft butter
- Blends with the flour into a paste and adds richness to the sauce.
The step that matters
Thicken the sauce with the flour and butter paste. Flour must be mixed smoothly into the butter first, then stirred into the milk and cooked fully. Otherwise lumps form and the sauce stays floury-tasting instead of smooth and thick.
Swap the beans
How well each one fits the dish's main ingredients (milk, flour, butter, pepper):
- Almondfits better
- Chestnutfits about as well
- Milletfits about as well
- Beansthe original
Fit is the average pairing score against milk, flour, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
