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

What each ingredient does

Tomatoes
Provide the main body and juicy flesh that absorbs the vinegar's flavor.
Cold vinegar
Adds acidity that sharpens flavor and helps keep the tomatoes preserved.
Whole pepper
Adds peppery aroma and mild heat as it infuses the vinegar.
Mustard seed
Adds a pungent, aromatic bite that develops as it steeps in the vinegar.

The step that matters

Wipe the tomatoes dry. Any water left inside the tomatoes dilutes the vinegar around them, weakening its acidity and flavor. Thorough drying keeps the vinegar strong enough to pickle the fruit and reduces the chance of spoilage in the jar.

Swap the tomato

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

  1. Horseradishfits better
  2. Radishfits better
  3. Lettucefits better
  4. Tomatothe original

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