Ingredients
Directions
Brine the cucumbers
Wash and wipe the cucumbers.
Pack the cucumbers tightly in a stone jar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Form the pickles, and their firm texture is what the brine and vinegar work on.
- Coarse sea salt
- Draws water out of the cucumbers and seasons them, firming the flesh for pickling.
- Cider vinegar
- Provides the acidity that preserves and sharply flavours the pickles.
- Brown sugar
- Balances the sourness of the vinegar with sweetness and adds depth.
- Black mustard seed
- Adds a sharp, pungent aroma and heat to the pickling liquid.
- Horseradish roots
- Adds a pungent, sharp bite that flavours the pickles.
The step that matters
Drain the pickles when cold. Cucumbers are mostly water, and residual brine or moisture dilutes the vinegar and weakens the pickle. Draining well keeps the pickling liquid strong and the texture firm.

Fit is the average pairing score against cucumber, cider, vinegar, sugar, pepper, horseradish, mustard. Candidates are from the same food group and used in at least 100 recipes.
