Why it works: Beans and rice match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 1,017 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Haricot Bean Soup
Ingredients
Directions
Prepare the beans
Soak the haricot beans in cold water overnight with a small piece of baking soda.
The next morning, place the beans in a saucepan with 3 pints of water, the onion, carrot, and salt.
Cook until the beans are tender.
Finish the soup
Pound the beans and strain through a wire sieve, discarding the onion and carrot.
Stir in the powdered sugar and butter just before serving.
Optionally, add a little rice to the soup.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Haricot beans
- Provide the main body and thickness of the soup once pounded and strained.
- Butter
- Adds richness and a smooth, silky mouthfeel to the finished soup.
- Powdered sugar
- Adds a little sweetness to balance the savoury flavour of the beans.
The step that matters
Cook until the beans are tender. Beans that are undercooked stay firm and grainy, so they will not pound into a smooth purée. Cooking until fully soft lets the starches break down so the strained soup becomes silky.
Swap the clove
How well each one fits the dish's main ingredients (beans, onion, carrot, butter, sugar, rice):
- Cinnamonfits better
- Cuminfits better
- Celeryfits better
- Clovethe original
Fit is the average pairing score against beans, onion, carrot, butter, sugar, rice. Candidates are from the same food group and used in at least 100 recipes.
