Why it works: Cabbage and horseradish match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 481 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Pickled Peppers
Ingredients
Directions
Prepare the peppers
Cut the peppers in half and remove the seeds.
Soak the peppers in strong salt water overnight.
Stuff and pack
Shred the cabbage and mix it with the celery seed, onions, and horseradish.
Drain the peppers and stuff them with the cabbage mixture.
Tie the halves together and place them in a stone jar.
Pickle and store
Heat the vinegar and sugar until boiling, then pour over the peppers.
Leave the peppers uncovered until cool, then cover securely.
Store in a cool place; they will be ready to serve in about three days.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green peppers
- Form the main vessel that is stuffed and holds the pickling brine.
- Cider vinegar
- Provides the acidity that preserves and sharpens the pickled peppers.
- Cabbage
- Supplies the crisp, bulky filling that fills the peppers.
- Silver skin onions
- Add a mild, sharp onion flavour to the cabbage filling.
- Sugar
- Balances the sharpness of the vinegar with a touch of sweetness.
The step that matters
Pour the boiling vinegar over the peppers, then cool uncovered. The vinegar must be fully boiling so the brine is hot enough to start pickling. Letting the peppers cool uncovered before sealing avoids trapping steam, which can soften them and encourage spoilage.
