Ingredients
Directions
Prepare the vegetables
Chop the cabbage, cauliflower, onions, green tomatoes, cucumbers, celery, and green peppers finely.
Boil the chopped vegetables in just enough water to cover until moderately soft, then strain.
Make the pickling liquid
Combine the vinegar, mustard, turmeric, white sugar, and salt in a separate pot.
Bring the mixture to a boil.
Pour the boiling mixture over the strained vegetables.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cabbage
- Forms the bulk of the relish and holds a firm, crisp texture after pickling.
- Green tomatoes
- Add tartness and body, and their pectin helps the relish thicken.
- Onions
- Contribute savory flavor and aroma that deepen during cooking.
- Vinegar
- Provides the acidity that preserves the vegetables and gives the relish its sharp taste.
- Mustard
- Adds pungent flavor and aroma that define the relish's character.
- White sugar
- Balances the sharpness of the vinegar and mustard with sweetness.
The step that matters
Boiling the vegetables until only moderately soft. Overcooking turns the vegetables mushy, while undercooking leaves them raw and crunchy. Since they then soak in hot pickling liquid, the texture set at this stage largely carries through to the finished relish.
