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

What each ingredient does

Celery
Provides the crisp, fresh bulk and vegetal flavor of the relish.
Red sweet peppers
Add sweetness and color to the relish.
Vinegar
Adds acidity that gives the relish its sharp, tangy flavor and preserves it.
Sugar
Balances the acidity with sweetness and helps thicken the relish as it cooks.

The step that matters

Boil the mixture for 1½ hours. Long simmering softens the vegetables and lets the liquid reduce, so the relish becomes thick and the flavors blend. Stopping early leaves it watery and sharp.

Swap the celery

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

  1. Cinnamonfits better
  2. Tarragonfits better
  3. Allspicefits better
  4. Celerythe original

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