Directions
Prepare the vegetables
Sprinkle cucumbers with salt and let them stand for 6 hours.
Squeeze cucumbers dry.
Scald cucumbers in a mixture of vinegar and water until cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Salting draws out water, leaving the pieces firmer and crisper after pickling.
- Cabbage
- Salting and pressing remove moisture, so the pickle stays crisp rather than watery.
- Onions
- Pressing after the vinegar rinse removes excess liquid, adding bite and body to the mix.
- White mustard seed
- Adds sharp, pungent flavour that mellows during pickling.
- Brown sugar
- Sweetness balances the sharpness of the vinegar and spices.
- Vinegar
- Acidity preserves the vegetables and gives the pickle its tang.
The step that matters
Pressing the vegetables dry. Excess water left in the cucumbers, cabbage and onions dilutes the vinegar brine and makes the pickle soft and watery. Squeezing or pressing them thoroughly keeps the texture crisp and the brine strong enough to preserve.
Swap the clove
How well each one fits the dish's main ingredients (cucumber, cabbage, onion, vinegar, horseradish, garlic, mustard):
- Capersfits better
- Dillfits better
