Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Yellow wax beans
Main vegetable; long slow simmering makes them very soft and tender.
Butter
Adds richness and a smooth, silky mouthfeel to the cooking liquid.
Flour
Thickens the cooking liquid, giving the beans a lightly body-rich coating.

The step that matters

Slow boiling for the full cooking time. Wax beans must simmer long enough to break down their fibrous cell walls and turn very soft. Stopping early leaves them tough, and a hard boil can break them apart before they are tender.

Swap the beans

How well each one fits the dish's main ingredients (butter, flour, beef):

  1. Almondfits better
  2. Chestnutfits about as well
  3. Peanutfits about as well
  4. Beansthe original

Fit is the average pairing score against butter, flour, beef. Candidates are from the same food group and used in at least 100 recipes.
