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, sliceable texture when cooked.
- Onions
- Add savory bulk and a mild sweetness that mellows during cooking and standing.
- Brown sugar
- Sweetens the pickling liquid and adds a molasses depth that balances the vinegar's sharpness.
- Vinegar
- Provides the acidity that preserves the pickles and gives them their tang.
- Ground mustard
- Adds sharp, pungent flavour to the pickling liquid.
The step that matters
Salting overnight and draining well. Salt draws water out of the tomatoes and onions by osmosis. Draining and rinsing afterward removes excess salt and surface water, so the pickles stay crisp-tender and do not taste overly salty or dilute the syrup.
Swap the tomato
How well each one fits the dish's main ingredients (onion, vinegar, sugar, mustard, allspice, clove, pepper):
- Horseradishfits better
- Shallotfits better
