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
