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

What each ingredient does

Green tomatoes
Provide the bulk of the pickle and firm texture when cooked only until tender.
White onions
Add savory flavour and soften during cooking, adding body to the pickle.
Coarse sea salt
Draws out moisture from the tomatoes and onions, helping them stay firm when cooked.
Vinegar
Provides acidity that preserves the pickle and sharpens its flavour against the sweetness.
Brown sugar
Adds sweetness and balances the sharpness of the vinegar.
Whole spices
Contribute aroma and warm flavour as they infuse into the vinegar and sugar syrup.

The step that matters

Cook until tender, but not soft. Overcooking breaks down the pectin and cell walls, turning the tomatoes mushy. Stopping when they are just tender keeps their shape and texture.

Swap the tomato

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

  1. Mustardfits better
  2. Cucumberfits better
  3. Capsicumfits better
  4. Tomatothe original

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