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
Prepare the fish
Skin and fillet the soles.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Soles
- Provide the delicate white flesh that cooks into tender pieces and flavour the soup.
- Stock
- Forms the liquid base of the soup and carries the flavour of the other ingredients.
- Onion
- Adds savory sweetness and aroma to the broth as it simmers.
- Celery
- Contributes aromatic, savory depth to the broth during long simmering.
The step that matters
Boil slowly for 3 to 4 hours. A gentle simmer extracts flavour from the bones and trimmings without clouding the broth. A rolling boil emulsifies fats and proteins, making the soup cloudy and harsher in taste.
Swap the mace
How well each one fits the dish's main ingredients (parsley, celery, onion, clove, pepper):
- Thymefits better
- Marjoramfits better
- Allspicefits better
- Macethe original
Fit is the average pairing score against parsley, celery, onion, clove, pepper. Candidates are from the same food group and used in at least 100 recipes.
