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

What each ingredient does

Kidney beans
Hold their shape during long simmering and add body and substance to the soup.
Black beans
Hold their shape during long simmering and add body and substance to the soup.
Chicken broth
Provides the liquid base that carries the vegetables and beans as they cook.
Onion
Softens and releases sweetness and savory depth when sautéed in oil.
Diced tomatoes
Add acidity and moisture that give the soup its tangy, rounded flavor.

The step that matters

Simmer covered on low heat for 2 hours. Once the broth boils, reducing the heat and keeping the pot covered lets the liquid simmer gently. A hard boil for this long can break down the beans and reduce the broth too much, so keep the heat low and check the liquid level.

Fit is the average pairing score against onion, garlic, chicken, sugar, corn, kidney beans, beans. 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).
