Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Form the crisp, bulky body of the pickle.
- White onions
- Add savory flavor and bulk to the pickled vegetables.
- Cabbage
- Adds crunch and bulk to the pickled mixture.
- Sugar
- Balances the sharpness of the vinegar with sweetness.
- White mustard seed
- Adds pungent, sharp flavor to the brine.
- Horseradish
- Contributes sharp, pungent heat to the dressing.
The step that matters
Draining the salted vegetables. Salt draws water out of the vegetables, and draining removes it. If they are not drained well, excess liquid dilutes the hot vinegar mixture and leaves the pickles soft and watery.
Swap the onion
