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):

  1. Parsleyfits better
  2. Capersfits better
  3. Thymefits better
  4. 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.
