Why it works: Tomato and olive are a kitchen classic. They rank in the top 1% of all ingredient pairs, and cooks put them together in 15,539 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dried beans
- Provide the main body and starch that thicken the soup as they soften.
- Cooked tomatoes
- Add acidity and body, giving the soup a brighter flavour.
- Olive oil
- Adds fat that carries flavour and gives the soup a smoother mouthfeel.
- Milk
- Adds richness and creaminess, softening the soup's flavour.
The step that matters
Mash the beans through a colander. Beans must be fully softened before mashing, since firm beans will not pass through and thicken the soup. Mashing releases starch, which gives body to the broth.
Swap the parsley
How well each one fits the dish's main ingredients (beans, tomato, olive, milk):
