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
- Baked beans
- Provide the main body and starch that give the soup its thick, hearty texture.
- Flour
- Thickens the soup when cooked with butter and stirred in, giving it body.
- Butter
- Cooks with the flour to form a roux that helps thicken and enrich the soup.
- Stewed tomatoes
- Add acidity and a fruity tang that balances the richness of the beans.
The step that matters
Adding the flour and butter. If the flour and butter are added without being cooked together first, the soup can taste raw and may form lumps. Cooking the roux briefly before stirring it in gives smooth thickening.
