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

What each ingredient does

Green tomatoes
Form the bulk of the pickle and soften into a tender, translucent texture when simmered.
Brown sugar
Adds sweetness and body to the vinegar, balancing its sharpness.
Strong vinegar
Provides the acidity that preserves the pickle and gives it its tang.
White mustard seed
Adds a sharp, pungent flavour that mellows during simmering.
Silver onions
Contribute sweetness and body to the pickle as they cook down.
Lemons
Add fresh citrus acidity and aroma to the pickle.

The step that matters

Simmer briskly until the tomatoes are clear. Simmering drives off excess moisture and softens the tomato cell walls so the pieces turn translucent and absorb the vinegar and sugar. Undercooked tomatoes stay firm and watery, while overcooking can break them down into a mush.

Swap the onion

How well each one fits the dish's main ingredients (tomato, coriander, pepper, lemon, mustard, sugar, ginger):

  1. Capsicumfits better
  2. Broccolifits better
