Why it works: Horseradish and mustard match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,832 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Martynia PICKLEs
Ingredients
Directions
Prepare the pods
Select young and tender martynia pods.
Soak pods in brine made with 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.
Make the pickle
Cover with equal parts cider vinegar and water, bring to a boil, then let stand for 30 minutes.
Drain and discard the weakened vinegar, then add 1.5 times the amount of pure cider vinegar.
For each gallon of vinegar, add 1 teacup sugar, ½ teacup grated onion, ½ teacup grated horseradish, 1 chopped green pepper, ½ teacup mustard seed, 1 tablespoon prepared mustard, 1 tablespoon whole cloves, 1 tablespoon black peppercorns, and ½ ounce mace in a cheesecloth bag.
Boil the mixture for 15 minutes and pour over the packed martynias in a jar.
Place the spice bag on top, weigh it down with a plate, and seal the jar once cooled.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Martynia pods
- Main vegetable; brining firms and tenderizes the pods so they stay crisp after pickling.
- Cider vinegar
- Provides the sour acidity that preserves the pods and gives the pickle its bright flavor.
- Sugar
- Balances the sharpness of the vinegar with sweetness.
- Horseradish
- Adds pungent heat that mellows as the pickle sits.
- White mustard seed
- Contributes sharp, pungent flavor that blooms in the hot vinegar.
The step that matters
Discarding the weakened vinegar. Draining off the first vinegar removes liquid diluted by the brine and pod juices, so the fresh, full-strength vinegar can properly acidify and preserve the pods.
