Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Oysters
Provide the main body and savoury, briny flavour of the catchup.
Cayenne pepper
Adds heat that gives the catchup its sharp, spicy character.
Wine
Adds acidity and liquid, helping to thin the mixture and carry the flavours.
Brandy
Adds aroma and a warm, spirited note added at the end.

The step that matters

Skim off any impurities. Oysters release foam and particles as they heat, and removing them keeps the finished catchup clear and clean-tasting rather than cloudy or bitter.

Swap the mace

How well each one fits the dish's main ingredients (oyster, pepper, wine, brandy):

  1. Thymefits better
  2. Clovefits better
  3. Rosemaryfits better
  4. Macethe original

Fit is the average pairing score against oyster, pepper, wine, brandy. Candidates are from the same food group and used in at least 100 recipes.
