Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Turkey-bone Soup
Ingredients
Directions
Make the soup
Break turkey bones apart with remaining meat and place in a soup kettle.
Add water, salt, red pepper, celery, potatoes, and onions.
Boil slowly for 4 hours, stirring occasionally.
Half an hour before serving, remove bones, skim off fat, and strain the soup.
If more soup is desired, add hot milk or water.
Make and add the force-meat balls
To make force-meat balls, mix chopped turkey meat, cracker crumbs, cayenne, salt, lemon peel, herbs, and beaten egg.
Roll mixture into balls the size of hickory nuts and drop into the soup 10 minutes before serving.
Serve
Serve the soup over chopped parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Turkey meat
- Provides the main protein and savory flavor of both the soup and the force-meat balls.
- Egg
- Binds the force-meat mixture so the balls hold their shape while cooking.
- Cracker crumbs
- Absorb moisture and help give the force-meat balls a firm, cohesive texture.
- Potatoes
- Break down during long simmering, adding body and thickening the soup.
The step that matters
Simmer gently and skim the fat. A slow boil for four hours extracts flavor from the bones, while removing fat before straining keeps the soup clear and less greasy.
Swap the onion
How well each one fits the dish's main ingredients (pepper, celery, potato, milk, meat, turkey, lemon):
- Carrotfits better

- Onionthe original
Fit is the average pairing score against pepper, celery, potato, milk, meat, turkey, lemon. Candidates are from the same food group and used in at least 100 recipes.
