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

What each ingredient does

Green tomatoes
Make up most of the pickle and soften into a tender, spoonable texture as they boil.
Sugar
Adds sweetness that balances the sharpness of the vinegar and helps the pickle brown as it cooks.
Strong vinegar
Provides acidity that sharpens the flavour and helps preserve the pickle.
Raw onions
Add savoury bulk and mellow sweetness as they cook down.
Green peppers
Add body and a mild, fresh vegetal flavour.
Ginger
Contributes warm, spicy aroma that rounds out the sweet and sour notes.

The step that matters

Boiling until soft and brown. Sugar and vinegar thicken and darken slowly as the liquid reduces. Sugars can scorch on the base of the pot if left unattended, giving a bitter taste, while too short a boil leaves the vegetables firm and the flavours raw.

Swap the onion

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