Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Provide the crisp, watery bulk that the pickle is built on.
- Cabbage
- Adds crunch and body that holds up through the pickling.
- Vinegar
- Acidity that preserves the vegetables and gives the pickle its tang.
- Sugar
- Balances the sharpness of the vinegar and mustard.
- White mustard seed
- Adds pungent, sharp flavour as the seeds soften in the hot brine.
The step that matters
Scald the mixture in vinegar. Heating the vegetables in vinegar softens them and lets the acid penetrate, but overheating turns them mushy. Keep it hot enough to scald, not to boil down the vegetables.
Swap the onion
