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

What each ingredient does

French beans
Form the body of the dish, becoming tender as they stew slowly in moisture.
Onion
Softens and sweetens gently in butter, adding a savory base flavor to the beans.
Butter
Adds richness and carries flavor while the onion softens without browning.
Broth or water
Provides the moisture that lets the beans stew until tender.

The step that matters

Cook the onion until softened but not browned. Browning the onion turns its flavor bitter and harsher, while gentle softening in butter builds a sweet, mellow base that carries through the whole dish.

Swap the walnut

How well each one fits the dish's main ingredients (onion, butter, beans, parsley, pepper):

  1. Chickpeafits better
  2. Black-eyed peafits better
  3. Lentilsfits better
  4. Walnutthe original

Fit is the average pairing score against onion, butter, beans, parsley, pepper. Candidates are from the same food group and used in at least 100 recipes.
