Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Provide the bulk of the pickle and absorb the brine and spiced vinegar flavor.
- Cucumbers
- Add crisp, watery texture that salting helps firm up before pickling.
- Sliced onions
- Contribute sharp flavor and aroma that mellows during the salted rest.
- Coarse sea salt
- Draws water out of the vegetables, firming them and helping preserve them.
- Vinegar
- Provides acidity that preserves the pickle and gives it its tang.
- Brown sugar
- Adds sweetness that balances the sharp acidity of the vinegar.
The step that matters
Draining after the 24-hour salt rest. Salt draws out a large amount of liquid from the vegetables. Draining thoroughly keeps the pickle from being watery and lets the vegetables absorb the spiced vinegar mixture rather than diluting it.
Swap the onion
