Ingredients
Directions
Brine the gherkins
Mix 2 pounds of salt into 1 gallon of spring water.
Add the gherkins to the saltwater.
Let the gherkins soak for 2 hours.
Drain the gherkins thoroughly.
Place the drained gherkins in a jar.
Make the pickling liquor
In a bell metal pot, combine vinegar, cloves, mace, allspice, mustard seed, horseradish, bay leaves, dill, ginger, nutmeg, and salt.
Bring the mixture to a boil.
Pour the boiling mixture over the gherkins in the jar.
Cover the jar tightly.
Let the jar sit for 24 hours.
Finish and store
Simmer the gherkins over low heat until they turn green, being careful not to boil them.
Cover the gherkins again.
Let them cool.
Seal the jar with a bladder and leather.
Store the sealed jar in a cool, dry place.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gherkins
- Provide the main body and crisp texture of the finished pickle.
- White wine vinegar
- Provides the acidity that preserves the gherkins and gives the pickle its sharp flavour.
- Sea salt
- Draws water out of the gherkins and seasons them before pickling.
- Mustard seed
- Adds a pungent, sharp aroma and flavour to the pickling liquor.
- Cloves
- Contribute warm, aromatic spice flavour to the pickling liquor.
The step that matters
Simmer the gherkins without boiling. Gentle heat lets the gherkins take on colour and warmth without the skins splitting or the flesh turning soft and mushy, which boiling would cause.
Swap the mace
