Why it works: Parsley and celery match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Fish Soup
Ingredients
Directions
Make the broth
Boil the fish in water with the vegetables and spices until cooked.
Remove the fish, cut off the flesh, and return the bones and trimmings to the saucepan.
Simmer gently for an hour, then strain the broth.
Finish and serve
Add the fish pieces back into the soup and heat through.
If desired, stir in sherry before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Provides the main protein and flavor, and its bones and trimmings give the broth body.
- Onions
- Add sweetness and savory depth as they cook into the broth.
- Celery
- Adds aromatic vegetable flavor to the broth.
- Parsley
- Contributes fresh herbal aroma to the broth.
The step that matters
Simmer gently for an hour. Keeping the broth at a gentle simmer rather than a hard boil extracts flavor from the bones and vegetables while keeping the liquid clear. A vigorous boil can cloud the broth and break up the flavor.
Swap the mace
How well each one fits the dish's main ingredients (fish, onion, parsley, celery, clove, sherry):
- Thymefits better
- Marjoramfits better
- Tarragonfits better
- Macethe original
Fit is the average pairing score against fish, onion, parsley, celery, clove, sherry. Candidates are from the same food group and used in at least 100 recipes.
