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 give it its tart, firm body.
- Onions
- Add savory sweetness and aroma that balance the sharp vinegar.
- Salt
- Draws water out of the sliced vegetables so they stay firmer in the brine.
- Vinegar
- Provides the acidity that preserves and sharpens the pickle.
- Brown sugar
- Adds sweetness and depth that offsets the acidity of the vinegar.
- Whole mustard
- Contributes pungent flavor and a sharp, tangy note to the brine.
The step that matters
Drain the salted tomatoes and onions before cooking. Salt draws out liquid overnight, and draining it fully before adding fresh water and vinegar keeps the pickle from becoming diluted and soft. Skipping the drain would change the brine's strength and texture.
Swap the onion
How well each one fits the dish's main ingredients (tomato, vinegar, sugar, mustard, cinnamon, allspice, clove):
- Horseradishfits better
- Capsicumfits better
