Why it works: Celery and parsley 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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Skate
- Provides the main body of fish flavour and gelatin that gives the soup body.
- Flounders
- Adds delicate fish flavour to the broth as they simmer.
- Eels
- Contribute rich flavour and body to the soup as they cook down.
- Butter
- Browns the fish when fried first, adding toasty, deeper flavour to the brown soup.
The step that matters
Simmer gently in a covered stew-pan. A gentle simmer extracts flavour and gelatin from the fish without breaking it up or making the broth cloudy. Boiling vigorously can emulsify fat and cloud the liquid, so keep the heat low and steady.
Swap the mace
How well each one fits the dish's main ingredients (pepper, onion, clove, celery, parsley, butter):
- Thymefits better
- Marjoramfits better
- Tarragonfits better
- Macethe original
Fit is the average pairing score against pepper, onion, clove, celery, parsley, butter. Candidates are from the same food group and used in at least 100 recipes.
