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 ↓
Chicken Soup
Ingredients
Directions
Prepare the stock
Remove all meat from the cold roast fowl, leaving only the wings and carcass.
Break the bones and place them in a soup kettle with 2 quarts of cold water and the cleaned neck and wings.
Dust the diced veal with flour and pepper, then brown it in 2 tablespoons of chopped bacon.
Add 1 cup of hot water to the browned veal, simmer for a few minutes, then pour into the soup kettle.
Cook slowly for 1 hour, then add the bay leaf, onion slice, and celery stalk; cook for an additional 30 minutes.
Strain the soup and cool it, then remove the fat and reduce the stock by one-fourth.
Make the thickened soup
In a saucepan, mix 2 tablespoons corn starch, 1½ teaspoons salt, ¼ teaspoon pepper, 1 tablespoon flour, and 2 tablespoons butter.
Gradually add 1 pint of hot stock and cook until thickened, then add 1½ cups of hot stock and mix well.
Stir in the beaten egg yolks diluted with 1 cup of cream, keeping the mixture hot but do not boil.
Serve
Serve in bouillon cups, optionally topped with a spoonful of whipped cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the soup and add richness as they set gently in the hot liquid.
- Cream
- Adds richness and a smooth, silky body to the finished soup.
- Corn starch
- Thickens the stock into a smooth, lightly bodied base when heated.
- Flour
- Helps thicken the butter-based base and browns the veal lightly.
- Butter
- Adds fat and flavor to the roux-style base that thickens the soup.
- Bacon
- Adds fat and savory flavor when used to brown the veal.
The step that matters
Stir in the egg yolks without boiling. Egg yolks thicken by gentle heat; if the mixture boils, the yolks can scramble and curdle, leaving the soup grainy instead of smooth.
Swap the onion
How well each one fits the dish's main ingredients (veal, flour, pepper, celery, corn, butter, egg):

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