Why it works: Carrot and turnip match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,002 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Bean Soup
Ingredients
Directions
Prepare the beans
Soak the beans overnight in 2 quarts of water.
In the morning, drain the beans and cover with fresh water.
Simmer the beans until tender, about 1-2 hours.
Make the soup
In a separate pot, heat the beef fat and sauté the chopped onion until translucent.
Add the cooked beans to the pot with the onion.
Season with coarse sea salt, black pepper, and red pepper.
If desired, add chopped and fried vegetables an hour before serving.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dried beans
- Form the body of the soup, becoming soft and creamy as they cook.
- Beef fat
- Carries flavor and adds richness to the onion and the finished soup.
- Onion
- Softens and sweetens as it cooks, building the savory base of the soup.
- Pork or a ham bone
- Releases savory flavor and body into the broth as it simmers.
The step that matters
Simmer the beans until tender. Dried beans must cook long enough to soften fully; undercooked beans stay firm and can be hard to digest. Adding salt only after the beans are tender helps prevent toughening during cooking.
Swap the beans
How well each one fits the dish's main ingredients (onion, beef, pepper, pork, carrot, turnip):
- Beansthe original
- Lentilsfits about as well
- Sesamefits less well
- Chestnutfits less well
Fit is the average pairing score against onion, beef, pepper, pork, carrot, turnip. Candidates are from the same food group and used in at least 100 recipes.
