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
Cut the peppers in half and remove the seeds.
Soak the peppers in strong salt water overnight.
Shred the cabbage and mix it with 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 to boiling, then pour over the peppers.
Leave the peppers uncovered until cool, then cover securely and 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
- Provide the crisp, hollow shell that holds the filling and softens slightly during pickling.
- Cider vinegar
- Supplies the acidity that preserves the peppers and gives the pickle its sharp flavor.
- Sugar
- Balances the sharpness of the vinegar with a mild sweetness.
- Cabbage
- Forms the crunchy, moist filling that fills the pepper halves.
- Celery seed
- Adds a warm, aromatic flavor to the cabbage filling.
- Horseradish
- Adds a sharp, pungent heat that complements the vinegar.
The step that matters
Soak the peppers in strong salt water overnight. Salt draws water out of the peppers through osmosis, firming them and reducing excess moisture so they stay crisp rather than watery once pickled.
Swap the onion
How well each one fits the dish's main ingredients (pepper, cider, vinegar, sugar, cabbage, celery, horseradish):
