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 ↓
Bean Soup
Ingredients
Directions
Make the broth
In a large pot, boil the beef, celery, tomatoes, and ham bone in 4 quarts of water.
Add the vegetables and thicken
Parboil the beans in a separate pot, then strain and add them to the soup.
Slice the onion and brown it in the butter, then add it to the soup.
In the same butter, brown the flour and stir it into the soup.
Finish cooking
Let the soup cook for 5 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Provides rich meaty flavor and body as it simmers into the broth.
- Beans
- Add starchy body and texture, becoming tender during the long simmer.
- Butter
- Carries the onion and flour, adding richness and helping them brown for flavor.
- Flour
- Browned in butter and stirred in, it thickens the soup slightly.
- Onion
- Browned in butter, it adds sweetness and savory depth.
- Ham bone
- Releases salty, smoky flavor into the broth during simmering.
The step that matters
Browning the flour in butter. Flour browned too quickly or too little can taste raw or burnt, and stirring it in unevenly leaves lumps. Cooking it gently until golden and whisking it into the soup helps it thicken smoothly.
