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 fowl
Pluck all feathers from the fowl and singe off hairs with lighted paper or alcohol.
Wipe the fowl with a wet towel, cut off the head and feet, and draw it carefully.
Make the soup
Peel and slice the onion, then fry it brown in a soup kettle with butter.
Add the fowl to the kettle and brown it slightly.
Pour in the cold water, add salt, pepper, diced celery, and mace.
Cover and boil slowly until the chicken is tender.
Prepare the head, feet, neck, gizzard, heart, and liver, then fry them brown in hot butter.
Add the fried parts to the soup and pour in hot water from the frying pan.
Once the fowl is tender, remove it for other uses and let the soup cook slowly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fowl
- Provides the main meat and flavour that gives the broth its body as it simmers.
- Onion
- Frying it brown adds sweetness and savoury depth to the broth.
- Butter
- Fat for browning the onion and giblets, adding roasted flavour.
- Celery
- Adds a fresh, aromatic vegetable flavour to the simmering broth.
The step that matters
Brown the onion and giblets before simmering. Browning in butter creates Maillard flavours that simmering alone cannot produce. Pale, undercooked browning leaves the broth tasting flat, while over-darkening can make it bitter.
Swap the mace
How well each one fits the dish's main ingredients (onion, butter, pepper, celery):
- Parsleyfits better
- Thymefits better
- Tarragonfits better
- Macethe original
Fit is the average pairing score against onion, butter, pepper, celery. Candidates are from the same food group and used in at least 100 recipes.
