Ingredients
Directions
Prepare the cucumbers
Select short thick cucumbers before they turn yellow.
Cut a small square piece from the side and remove all seeds using a marrow spoon.
Soak the cucumbers and cut pieces in strong salt and water for three days.
Lay them on a cloth to dry.
Colour in vinegar
Line a preserving pan with vine leaves and add the cucumbers and cut pieces.
Add sliced ginger and fill the pan with vinegar.
Cover with a plate to trap steam and place by the fire until the cucumbers turn green, being careful not to boil them.
Once they are a good color, remove them from the vinegar and let them cool.
Reserve the vinegar in a jar.
Fill and seal
Prepare the filling by scraping horseradish finely, adding mustard seeds, chopped garlic, chopped shallots, and a little cayenne.
Fill the cucumbers with the mixture, replace the cut piece, and tie with packthread to secure.
Boil the reserved vinegar, adding mace, cloves, long peppers, mustard seed bag, and sliced garlic.
Boil for five minutes.
Pour the hot vinegar over the filled cucumbers and seal the jar with a bladder.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Short thick cucumbers
- Form the main body of the pickle, staying firm and crisp through the long brining.
- Strong salt
- Draws water out of the cucumbers during soaking, firming the flesh and preparing it to take up flavour.
- Vinegar
- Acidic liquid that preserves the cucumbers and gives the pickle its sharp, sour taste.
- Horseradish
- Supplies a pungent, sharp heat that flavours the filling.
- Mustard seeds
- Add a sharp, pungent flavour to the filling and the spiced vinegar.
- Garlic
- Adds a strong savoury aroma and pungency to the filling and the spiced vinegar.
The step that matters
Keep the vinegar below a boil while colouring the cucumbers. Heating the cucumbers too hard softens their structure and turns them mushy. Gentle warmth lets them turn green while staying firm, and the steam under the plate keeps the heat even.
Swap the ginger
How well each one fits the dish's main ingredients (cucumber, vinegar, horseradish, mustard, garlic, shallot, pepper):
- Capersfits better
