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

What each ingredient does

Green tomatoes
Provides the bulk of the relish and its tart, fresh flavor.
Cabbage
Adds body and a crisp-tender texture after simmering.
White mustard seed
Contributes sharp, pungent flavor that deepens as the relish cooks in vinegar.
Ground mustard
Adds mustard flavor and helps thicken and season the mixture.
Vinegar
Provides acidity that preserves the vegetables and gives the relish its tang.

The step that matters

Simmer until the vegetables are sufficiently cooked. Vegetables of different densities soften at different rates. Simmering long enough to tenderize the dense cauliflower and string beans, without overcooking the softer tomatoes, gives an even texture.

Swap the onion

How well each one fits the dish's main ingredients (tomato, cabbage, cucumber, cauliflower, pepper, beans, mustard):

  1. Lettucefits better
  2. Broccolifits better
  3. Horseradishfits better
  4. Onionthe original

Fit is the average pairing score against tomato, cabbage, cucumber, cauliflower, pepper, beans, mustard. Candidates are from the same food group and used in at least 100 recipes.
