Martynia PICKLEs
Ingredients
Directions
Prepare the pods
Select young Martynia pods and pierce them with a nail.
Soak the pods in a brine of 1 teacup salt and 1 gallon water for 3 days, keeping them submerged with a plate.
Drain the pods and place them in a preserving kettle.
Cover the pods with equal parts cider vinegar and water, bring to a boil, then let stand for 30 minutes.
Drain and discard the weakened vinegar.
Make the pickling syrup
Add 1½ times the quantity of pure cider vinegar to the kettle.
For each gallon of vinegar, add 1½ teacups sugar, ½ teacup grated raw onion, ½ teacup grated horseradish, 1 chopped green pepper, ½ teacup white mustard seed, 1 tablespoon prepared mustard, 1 tablespoon whole cloves, 1 tablespoon black peppercorns, and ½ ounce mace.
Tie the spices and other ingredients in a cheesecloth bag and add to the kettle.
Boil the mixture for 15 minutes and pour over the packed Martynia pods in a jar.
Seal and store
Place the spice bag on top, keep it down with a plate, and when cool, seal tightly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Martynia pods
- Main vegetable; the firm, young pods hold their crispness through brining and pickling.
- Salt
- Draws water out of the pods during the brine, firming their texture and seasoning them.
- Cider vinegar
- Acid that preserves the pods and gives the pickle its sharp, tangy flavour.
- Sugar
- Balances the sharpness of the vinegar and rounds out the sweet-sour flavour.
- White mustard seed
- Adds a pungent, earthy bite that carries through the pickling liquid.
- Horseradish
- Contributes a sharp, pungent heat that deepens the pickle's flavour.
The step that matters
Soaking the pods in the vinegar and then draining it off. Brining and then discarding the first vinegar removes excess water and bitterness, so the pods stay firm and the fresh vinegar preserves them properly rather than being diluted.
Swap the onion
How well each one fits the dish's main ingredients (cider, vinegar, sugar, horseradish, pepper, mustard, clove):
- Shallotfits better
- Radishfits better
- Beetrootfits better
- Onionthe original
Fit is the average pairing score against cider, vinegar, sugar, horseradish, pepper, mustard, clove. Candidates are from the same food group and used in at least 100 recipes.
