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 ↓
Italian Soup
Ingredients

Wash and shred the savoy cabbage, then add it to the stewpan.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Haricot beans
- Hold their shape while adding body and starch that thickens the soup.
- Savoy cabbage
- Adds bulk and a tender, slightly sweet vegetable texture as it cooks down.
- Rice
- Releases starch as it cooks, thickening the broth and giving the soup body.
- Smoked sausages
- Contribute smoky, savoury flavour and fat that enriches the broth.
- Raw ham
- Flavours the broth with savoury, salty meat richness as it simmers.
- Chopped bacon
- Renders fat and smoky savouriness into the broth as it cooks.
The step that matters
Simmer until the rice is cooked. Rice keeps absorbing liquid and releasing starch as it sits, so it can turn mushy or over-thicken the soup if simmered too long. Gentle heat keeps the soup at a steady simmer rather than a hard boil, which would break up the vegetables and beans.
Swap the cabbage

Fit is the average pairing score against ham, beans, celery, peas, asparagus, rice, tomato. Candidates are from the same food group and used in at least 100 recipes.
