Why it works: Cabbage and mustard match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 1,645 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Pickled Green Peppers
Ingredients
Directions
Prepare the peppers
Cut a slit in the side of each pepper to remove the seeds, keeping them whole.
Make a strong brine and pour it over the peppers; let them stand for 24 hours.
Remove the peppers from the brine and soak them in water for 1 day and 1 night.
Drain the water and scald some vinegar with a small piece of alum; pour it over the peppers and let them stand for 3 days.
Stuff and pickle
Prepare a stuffing by mixing the chopped cabbage with a little salt and the mustard seed.
Stuff the peppers tightly with the mixture and stitch them up.
Place the stuffed peppers in a stone jar and pour hot spiced vinegar over them. Cover the jar tightly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green bell peppers
- Provide the main body of the pickle, which softens and absorbs the brine and vinegar flavour.
- White cabbage
- Forms the crisp, chopped stuffing that fills the peppers and adds texture.
- White mustard seed
- Adds a sharp, pungent flavour to the stuffing as the pickle matures.
- Vinegar
- Provides the acidity that preserves the peppers and gives the pickle its sharp taste.
The step that matters
Soaking in the brine and water. Salt draws water out of the peppers and makes them firm, while the later soak in water removes excess salt. Skipping or shortening these soaks can leave the peppers too salty or too soft to hold the stuffing.
Swap the cabbage
How well each one fits the dish's main ingredients (pepper, vinegar, mustard):
- Horseradishfits better
- Radishfits about as well
- Lettucefits about as well
- Cabbagethe original
Fit is the average pairing score against pepper, vinegar, mustard. Candidates are from the same food group and used in at least 100 recipes.
