Why it works: Beans and carrot match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 1,443 recipes. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓
Brown Haricot Soup
Ingredients
Directions
Prepare the beans
Soak the beans overnight, then wash them.
Put the beans in a pan with water and bring to a boil.
If possible, pass the beans through a sieve and return them to the pan.

Add the chopped carrots and onions, and cook until tender.
Half an hour before serving, add the suet dumplings.
A few minutes before serving, stir in the milk.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Brown haricot beans
- Form the body of the soup and thicken it as they break down.
- Onions
- Add savoury sweetness and aroma as they soften.
- Carrots
- Add natural sweetness and a soft texture when cooked until tender.
- Milk powder
- Adds richness and creaminess to the soup.
- Flour
- Thickens the soup and gives it body.
The step that matters
Passing the beans through a sieve. Pushing the cooked beans through a sieve breaks them into a smooth purée that thickens the liquid. Skipping this leaves the soup thin and grainy in texture.
Swap the onion
How well each one fits the dish's main ingredients (beans, carrot, milk powder, flour, pepper):
- Capsicumfits better
- Parsnipfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against beans, carrot, milk powder, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
