Why it works: Mustard and radish match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 297 recipes. Both carry eucalyptol, which smells eucalyptus, herbal. The science ↓
Pepper Mangoes
Ingredients
Directions
Prepare the peppers
Cut the tops off the bell peppers, leaving the stems to form lids.
Scrape out the seeds.
Soak the peppers in salt water overnight, using 1 cup of salt per pail of water.
Drain the peppers upside down on a tray.
Make the filling
Chop fresh cabbage very fine.
For each gallon of chopped cabbage, mix in 1 cup sugar, 1 tablespoon white mustard seed, 1 tablespoon black mustard seed, and 1 tablespoon celery seed.
Let the mixture stand for 1 hour.
Squeeze the cabbage mixture to remove excess moisture.
Stuff the peppers tightly with the mixture.
Pack and pickle
Place a lid on each stuffed pepper and secure with 3 wooden toothpicks.
Pack the peppers into a 2 or 3-gallon stone jar, leaving space for a plate and weight.
Add several horse radish roots on top and sprinkle ½ cup sugar into the jar to prevent spoilage.
Cover the peppers with cider vinegar, ensuring they are submerged. Use a plate and weight if necessary.
Seal the jar with thick paper.
Store in a cool place; they will keep for a year.
Serve
Remove the toothpicks and lid, and serve the mangoes in a pickle dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bell peppers
- Form the edible container that holds the filling and keeps its shape.
- Fresh cabbage
- Provides the bulk of the filling and a crisp, crunchy texture after pickling.
- Mustard seed
- Adds a sharp, pungent flavour that mellows during pickling.
- Sugar
- Adds sweetness that balances the sharpness of the vinegar.
- Cider vinegar
- Adds acidity that flavours the pickle and helps preserve it.
The step that matters
Keep the peppers fully submerged in the vinegar. Peppers left above the liquid are exposed to air, which lets mould and spoilage microbes grow on the surface. Covering everything with vinegar and weighting it down keeps the acidic brine in contact with the whole pickle.
