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 extract the seeds, keeping them whole.
Make a strong brine and pour it over the peppers.
Let the peppers stand for 24 hours.
Remove the peppers from the brine.
Soak the peppers in water for 1 day and 1 night.
Drain the water.
Pickle in vinegar
Scald vinegar with a small piece of alum.
Pour the scalded vinegar over the peppers.
Let the peppers stand for 3 days.
Stuff and jar
Prepare a stuffing by mixing the chopped cabbage with a little salt and the mustard seed.
Stuff the peppers tightly with the mixture.
Stitch the peppers up.
Place the stuffed peppers in a stone jar.
Pour scalding hot spiced vinegar over the peppers and 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
- Their flesh becomes tender and crisp-firm after brining and soaking, holding the stuffing.
- White cabbage
- Fills the peppers and, once pickled, adds crunch and a sharp, tangy bulk.
- White mustard seed
- Adds a pungent, sharp flavour to the cabbage stuffing as it pickles.
- Vinegar
- Acidity preserves the peppers and gives the pickle its sour, tangy character.
The step that matters
Stuffing the peppers tightly. Packing the cabbage firmly leaves little air around the filling, which helps keep the peppers submerged and reduces spoilage risk in the jar. Loose stuffing can let peppers float or collapse.
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.
