Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Firm, tart vegetable base that holds its shape and adds bulk to the pickle.
- Coarse sea salt
- Draws water out of the chopped vegetables, firming them and concentrating flavor before cooking.
- Vinegar
- Provides the acidity that preserves the pickle and gives it its sharp taste.
- Dark brown sugar
- Balances the vinegar's sharpness with sweetness and adds depth through its molasses flavor.
- Onions
- Add savory bulk and sweetness that softens during the long cook.
The step that matters
Drain the vegetables well. Salted vegetables hold a lot of liquid. If excess brine stays in, it dilutes the vinegar and sugar syrup, making the pickle watery and overly salty.
Swap the onion
How well each one fits the dish's main ingredients (tomato, celery, pepper, cabbage, cucumber, vinegar, sugar):
- Capsicumfits better
