Why it works: Cucumber and mustard match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 2,281 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Pickled Peppers
Ingredients
Directions
Prepare
Make a small incision in the side of each pepper and remove all the seeds carefully.
Soak the peppers in brine for two days, changing the water twice.
Stuff and pickle
Stuff the peppers with a mixture of chopped cabbage or tomatoes seasoned with spices, or a mixture of nasturtiums, chopped onions, red cabbage, grapes, and cucumbers seasoned with mustard seed and a little mace.
Sew up the incision, place the stuffed peppers in a jar, and cover with cold-spiced vinegar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Large green sweet peppers
- Serve as the hollow vessel that holds the stuffing and pickling liquid.
- Cold-spiced vinegar
- Provides the acidity that preserves and sharpens the pickled peppers.
- Brine
- Draws out moisture and mellows the peppers before stuffing.
The step that matters
Soaking the peppers in brine for two days. Brine softens the peppers and draws out some water, so they take up the stuffing and vinegar better. Changing the water twice keeps the salt level from building up and stops the soak from going sour or too salty, which would spoil the flavour of the finished pickle.
Swap the mace
How well each one fits the dish's main ingredients (pepper, egg, cabbage, onion, grape, cucumber, mustard):
- Dillfits better
- Capersfits better
- Tarragonfits better
- Macethe original
Fit is the average pairing score against pepper, egg, cabbage, onion, grape, cucumber, mustard. Candidates are from the same food group and used in at least 100 recipes.
