Why it works: Carrot and celery match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,173 recipes. Both carry myristicin, which smells spice, warm. The science ↓
Bean Soup
Ingredients
Directions
Prepare
Soak the beans overnight in lukewarm water.
In the morning, drain the beans and place them in a kettle with 1 gallon of cold water and 1 pound of salt pork.
Add 2-3 onions, 1 carrot, a little red pepper, and coarse sea salt to taste.
Cook and serve
Boil slowly for 3 hours, keeping the pot covered.
Finely chop the head of celery and add it to the pot.
Strain the soup through a colander or sieve and return it to the fire.
Serve hot with slices of lemon.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beans
- Provide the body and starch that thicken the soup as they cook down.
- Salt pork
- Adds fat and savory depth that carries the flavor of the broth.
- Onions
- Contribute sweetness and aromatic flavor as they soften in the broth.
- Celery
- Adds aromatic, vegetal flavor to the broth.
The step that matters
Boil slowly, keeping the pot covered. A slow simmer lets the beans soften fully without breaking apart or scorching on the bottom. Keeping the lid on holds in moisture and heat so the beans cook evenly over the three hours.

Fit is the average pairing score against beans, pork, onion, carrot, pepper, celery. Candidates are from the same food group and used in at least 100 recipes.
