Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Forms the bulk of the pickle and gives it a crisp bite.
- White vinegar
- Supplies the acidity that sharpens the pickle and helps preserve it.
- Horseradish
- Adds sharp, pungent heat to the pickle.
- Brown sugar
- Balances the vinegar's sharpness with sweetness and depth.
- Green peppers
- Adds bulk, a mild bitterness and crisp texture.
- White onions
- Adds savory sharpness and bulk to the mix.
The step that matters
Add the soaked vegetables to the boiling vinegar mixture and bring to a boil. The vinegar must be fully boiling before the vegetables go in so the pickle heats quickly. Vegetables held in hot acid too long soften and lose their crunch, so timing matters.
Swap the onion
