Ingredients
Directions
Prepare the peppers
Cut a slit in the side of the bell peppers and remove the seeds and pulp.
Pour boiling water over the peppers and let them stand for 24 hours, then drain.

Scald the peppers every morning for 5-6 days until they turn green.
Cover the peppers with grape or cabbage leaves.
Drain the peppers.
Wipe the peppers dry.
Make the dressing and stuff
Mix the chopped cabbage, white mustard seed, grated horseradish, black mustard seed, celery seed, and ground ginger together.
Add small white onions, cucumbers, string beans, and nasturtiums to the mixture.
Stuff the peppers with the dressing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bell peppers
- Form the pickle's body, becoming tender and green as they are scalded and then stuffed.
- Coarse sea salt
- Draws moisture out of the peppers and seasons the brine that preserves them.
- Saltpeter
- Helps the peppers keep a green color during repeated scalding.
- Cabbage
- Provides the bulk and crisp texture of the stuffing.
- Horseradish
- Adds sharp pungency that mellows during pickling.
- Vinegar
- Provides acidity that preserves the peppers and keeps them firm.
The step that matters
Keep the peppers covered with vinegar. Peppers exposed to air can soften and spoil in the jar. Keeping them fully submerged in acidic vinegar helps them stay firm and preserved.
Swap the ginger
How well each one fits the dish's main ingredients (pepper, vinegar, cabbage, mustard, horseradish, celery, onion):
- Tarragonfits better
- Dillfits better
- Capersfits better
