Ingredients
Directions
Brine
Dissolve 1 lb coarse sea salt in 2 quarts water in an earthenware jar and add the gherkins.
Let the gherkins soak for 2 hours, then drain them on a sieve and let them dry completely.
Pickle
In a pot, boil 2 quarts white vinegar with 1/2 oz cloves, 1/4 oz mace, 1/2 oz allspice, 2 oz ginger, 1/4 oz mustard seed, 1/2 stick horseradish, 3 bay leaves, 1/2 nutmeg, and a little salt.
Pour the hot vinegar mixture over the gherkins, cover the jar tightly, and let it sit for 24 hours.
Place the jar in a stewpan and simmer on low heat until the gherkins turn green, ensuring they do not boil.
Transfer the gherkins to jars or wide-mouthed bottles, cover them, and let them cool.
Seal the jars with corks tied with leather and store in a dry place.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gherkins (in the method)
- Are the main food being preserved; brining firms and prepares them to take up the vinegar.
- Coarse sea salt
- Draws water out of the gherkins during the brine, firming them and seasoning the pickle.
- White vinegar
- Provides the acidity that preserves the gherkins and gives the pickle its sharp flavor.
- Ginger
- Adds aromatic warmth and pungency to the pickling liquid.
- Cloves
- Contribute warm, aromatic spice flavor to the pickling liquid.
- Mustard seed
- Adds a sharp, pungent spice note to the pickling liquid.
The step that matters
Keep the gherkins below a boil when they turn green. Gentle simmering lets the gherkins color and soften while keeping their texture intact. Boiling makes them mushy and can break down their structure.
Swap the mace
