Why it works: Celery and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Black Bean Soup
Ingredients
Directions
Prepare the beans
Soak the black beans overnight, then drain.
Add the beans to a pot with cold water and the seasonings tied in cheesecloth.
Boil slowly until the beans are tender, adding water as needed.
Make the soup
Once soft, remove the seasonings and mash the beans through a sieve.
Stir the stock into the mashed beans.
Melt the butter, mix in the flour, and gradually stir this into the stock.
Season with salt and pepper.
Serve
In a tureen, add the sherry wine, lemon slice, egg balls, and diced egg white just before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Black beans
- Form the body of the soup once cooked and mashed through a sieve.
- Butter
- Carries flavor and, with flour, forms a roux that thickens the soup.
- Flour
- Thickens the stock when cooked in butter and stirred in.
- Sherry wine
- Adds a sweet, aromatic note when added to the tureen before serving.
The step that matters
Stirring the flour and butter into the stock. Flour lumps if added directly to hot liquid. Cooking it in melted butter first coats each grain, letting it disperse smoothly and thicken the soup evenly.
Swap the onion
How well each one fits the dish's main ingredients (beans, butter, flour, celery, clove, parsley, pepper):
- Carrotfits better

- Onionthe original
Fit is the average pairing score against beans, butter, flour, celery, clove, parsley, pepper. Candidates are from the same food group and used in at least 100 recipes.
