Ingredients
Directions
Make the mustard base
In a bowl, mix mustard with salad oil and a little vinegar until smooth. Add cinnamon, white pepper, cayenne pepper, horseradish, ginger, and celery seed.
Stir in brown sugar.
Cook and pack
Transfer to a stone jar filled two-thirds with vinegar.
Place the jar in a vessel of cold water over heat and boil for 2-3 hours, stirring occasionally.
After boiling, add white mustard seed and turmeric.
Fill the jar with cut cabbage, beans, corn, onions, and cucumbers.
Add more vegetables as needed.
Store
Store the pickle for 1-2 years.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mustard
- Forms the main body and sharp flavour of the pickle.
- Salad oil
- Adds fat that helps carry spice flavour and smooth the mustard paste.
- Brown sugar
- Adds sweetness that balances the sharpness of mustard and vinegar.
- Vinegar
- Provides acidity that preserves the pickle and sharpens its taste.
- White mustard seed
- Adds texture and a mild pungent bite to the finished pickle.
- Cabbage
- Supplies the main vegetable bulk that soaks up the mustard dressing.
The step that matters
Boiling the jar in water over heat. Gentle, prolonged heating lets the mustard base blend and mellow with the vinegar. Stirring keeps the mustard from settling and scorching on the bottom.
Swap the white pepper
How well each one fits the dish's main ingredients (mustard, vinegar, cinnamon, pepper, horseradish, ginger, celery):
- Allspicefits better
- Turmericfits better
- Clovefits better
- White pepperthe original
