Why it works: Onion and celery are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 18,518 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish trimmings
- Provide the main flavour base of the stock as they simmer in the water.
- Onion
- Adds subtle sweetness and aroma to the stock.
- Celery
- Adds aromatic depth to the stock's overall flavour.
The step that matters
Skim the surface thoroughly. Skimming removes coagulated proteins and impurities that rise as the liquid heats. Removing them keeps the stock clear and prevents off, cloudy flavours from developing during simmering.
Swap the mace
How well each one fits the dish's main ingredients (fish, onion, celery):
- Parsleyfits better
- Capersfits better
- Thymefits better
- Macethe original
Fit is the average pairing score against fish, onion, celery. Candidates are from the same food group and used in at least 100 recipes.
