Directions
Prepare the vegetables
Sprinkle salt over the sliced cucumbers, chopped cabbage, onions, and bell peppers, then let stand for 12 hours.
Press out excess moisture with your hands.
Cook and seal
In a porcelain kettle, layer the chopped vegetables with the spices: white mustard seed, turmeric, celery seed, ground mustard, and sugar.
Cover the mixture with cider vinegar and boil until it begins to thicken.
Seal while hot.

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 of the relish that stays crunchy after pickling.
- Cabbage
- Adds body and crunch to the relish as it cooks down.
- Cider vinegar
- Provides the acidity that preserves and sharpens the relish.
- Sugar
- Balances the sharp vinegar with sweetness and helps soften the mixture.
- White mustard seed
- Contributes pungent, sharp flavour as the spices release into the vinegar.
The step that matters
Pressing out the moisture after salting. Salt draws water out of the sliced vegetables. Pressing out the excess keeps the relish from diluting the vinegar, which helps it thicken and stay crisp rather than soggy.
Swap the onion
