Why it works: Beans and tomato match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 2,713 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Black beans
- Form the body of the soup and thicken it as they break down during long cooking.
- Beef
- Adds savory, meaty depth to the broth during the long simmer.
- Ham
- Contributes salty, smoky richness to the broth.
- Tomatoes
- Add acidity and body, balancing the rich meat and beans.
- Butter
- Adds fat and a smooth, rounded mouthfeel to the finished soup.
The step that matters
Boil for four hours. A long, steady simmer is needed to soften dried beans fully and extract flavor from the meat. Too little time leaves the beans firm and the broth thin.
