Why it works: Tomato and beans 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
- Beef shank
- Slow simmering draws flavor and body from the meat and bone into the broth.
- Tomatoes
- Add acidity and body, giving the broth a rounder, brighter flavor.
- Potatoes
- Their starch softens during simmering and adds body to the broth.
- Flour
- Its starch swells in hot liquid and thickens the soup.
- Butter beans
- Soften during simmering and add a creamy texture and substance.
- Corn
- Adds natural sweetness and a tender bite.
The step that matters
Thickening with flour and water. Flour should be mixed smoothly with water before it goes in, so it does not clump. Its starch only thickens the soup once it is hot, so the mixture must be stirred into the simmering soup and given time to set the body.
Swap the onion
How well each one fits the dish's main ingredients (beef, tomato, potato, butter, beans, corn, flour):

- Onionthe original
Fit is the average pairing score against beef, tomato, potato, butter, beans, corn, flour. Candidates are from the same food group and used in at least 100 recipes.
