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.
Sherry
Adds acidity and aromatic depth, and helps extract flavour from the oysters.
Mace
Contributes a warm, aromatic spice flavour.
Cayenne pepper
Adds heat and a sharp, pungent note to balance the oysters.

The step that matters

Rub the mixture through a sieve. Skimming and sieving remove solid pieces and fat, so the catchup becomes smooth and clear. Leftover solids can spoil the sauce during storage.

Swap the mace

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

  1. Thymefits better
  2. Parsleyfits better
  3. Marjoramfits better
  4. Macethe original

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