Why it works: Pepper and celery 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 ↓
Dried Bean Soup
Ingredients
Directions
Prepare
Soak the dried white beans overnight.
Cut the beef into pieces and place in a soup pot with the bones, broken into pieces.
Add the lean bacon, cut into small pieces.
If available, add any leftover undercooked roasted beef and its bones.
Season the meat with pepper and pour in 6 quarts of water.
Cook
Bring to a boil, skimming off any scum.
Drain the soaked beans and add them to the pot along with the chopped celery or celery seed.
Boil slowly until the meat is tender and the beans are dissolved.
Serve
Strain the soup through a colander into a tureen.
Add small squares of toasted bread to the soup before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dried white beans
- Break down during long simmering to thicken the soup and give it body.
- Beef
- Releases flavour and gelatin into the broth as it simmers until tender.
- Bacon
- Adds smoky, savoury fat that enriches the broth's flavour.
- Celery
- Contributes aromatic, savoury flavour to the broth.
The step that matters
Boil slowly until the meat is tender and the beans are dissolved. A gentle simmer lets collagen in the meat break down into gelatin while the beans soften and break apart. A hard, rapid boil can toughen meat proteins and cloud the broth.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
