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 ↓
Baked Bean Soup
Ingredients
Directions
Combine the baked beans, water, onion, and celery in a pot.
Simmer for 30 minutes.
Rub the mixture through a sieve.

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 thickens the soup as they break down.
- Stewed and strained tomatoes
- Add acidity and a rounded, savoury flavour to the soup.
- Butter and flour
- Form a paste that thickens the soup and adds richness.
The step that matters
Rubbing the mixture through a sieve. Pressing the simmered beans through a sieve breaks them into a smooth purée. Skipping or rushing this leaves the soup grainy and uneven in body.
Swap the onion
How well each one fits the dish's main ingredients (beans, celery, tomato, pepper, butter, flour):
- Okrafits better
- Capsicumfits better
- Carrotfits better
- Onionthe original
Fit is the average pairing score against beans, celery, tomato, pepper, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
