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

What each ingredient does

Yellow wax beans
Provide the main vegetable, which softens into tender pieces during long, slow boiling.
Butter
Adds richness and a smooth mouthfeel to the cooking liquid.
Flour
Thickens the cooking liquid slightly so it clings to the beans.
Beef broth
Adds savory flavor to the cooking liquid if used.

The step that matters

Adding the butter and flour after 2 hours. Flour mixed into hot liquid can clump if it is not blended with the butter first. Stirring the butter and flour together before adding them to the beans helps them disperse evenly and thicken the liquid smoothly.

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.
