Why it works: Celery and pepper match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 16,012 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Bean Soup
Ingredients
Directions
Prepare the beans
Soak the beans overnight.
In the morning, boil the beans until tender.
Make the soup
Simmer the beef bone, bacon, celery, and onion in water for three hours to make stock.

Season with salt and pepper to taste.
Serve
Place croutons in a soup tureen and pour the soup over them.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beans
- Their starch thickens the soup as they are mashed into the stock, giving it body.
- Beef bone
- Simmering releases gelatin and flavor, giving the stock depth and body.
- Bacon
- Its rendered fat and smoky flavor enrich the stock.
- Onion
- Releases sweet, savory aromatics that build the flavor base of the stock.
- Celery
- Adds vegetal aroma that rounds out the flavor of the stock.
The step that matters
Mash the beans through a colander and add to the stock. Mashing the cooked beans breaks down their starch-rich cells so they dissolve into the liquid and thicken the soup. Beans must be fully tender first, or they will stay grainy and the soup will not thicken evenly.
Swap the beans
How well each one fits the dish's main ingredients (beef, celery, onion, pepper):
- Beansthe original
- Black-eyed peafits about as well
- Sesamefits about as well
- Lentilsfits less well
Fit is the average pairing score against beef, celery, onion, pepper. Candidates are from the same food group and used in at least 100 recipes.
