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

What each ingredient does

Green peppers
Form the bulk of the sauce and soften into a mashable pulp when boiled.
Onions
Add body and savory sweetness as they soften into the sauce.
Cider vinegar
Provides acidity that gives the sauce its sharp flavor and helps preserve it.
Horseradish
Adds a sharp, pungent heat that fades somewhat with cooking.

The step that matters

Mash the peppers through a sieve while soft. Boiling until the peppers are fully soft lets them pass through the sieve smoothly. Under-cooked peppers stay fibrous and leave a coarse, uneven texture in the sauce.

Swap the mace

How well each one fits the dish's main ingredients (pepper, onion, garlic, horseradish, cider, vinegar, allspice):

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

Fit is the average pairing score against pepper, onion, garlic, horseradish, cider, vinegar, allspice. Candidates are from the same food group and used in at least 100 recipes.
