Why it works: Mustard and horseradish match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,832 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Pepper Mangoes
Ingredients
Directions
Prepare the peppers
Cut the tops off the peppers and remove the seeds, saving the tops.
Stand the peppers upright in a tub and add 1 teaspoon of salt to each, then cover with cold water and soak overnight.
In the morning, drain and wash the peppers well in cold water.
Stuff and pickle
Shred the cabbage using a slaw cutter and mix with allspice, mustard seeds, salt, and mace if desired.
Stuff the mixture into the peppers, replace the tops, and tie with soft twine.
Stand the stuffed peppers upright in stone jars and cover with cold vinegar.
Let them sit for one week, then drain off the vinegar.
Cover with fresh cold vinegar and add nasturtiums or horseradish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cabbage
- Forms the bulk of the filling, adding crisp texture that holds up through pickling.
- Mustard seeds
- Add a sharp, pungent flavour that mellows as the peppers pickle.
- Vinegar
- Acidifies the peppers, preserving them and giving the pickle its tang.
- Salt
- Draws water out of the peppers during soaking, firming their flesh and seasoning the filling.
The step that matters
Draining and re-covering with fresh vinegar after one week. Vinegar that has sat with the peppers picks up their liquid and loses strength, so replacing it with fresh cold vinegar keeps the acidity high enough to preserve the pickle.
Swap the mace
The recipe marks mace as optional. How well each one fits the dish's main ingredients (pepper, cabbage, allspice, mustard, horseradish, vinegar):
- Tarragonfits better
- Dillfits better
- Capersfits better
- Macethe original
Fit is the average pairing score against pepper, cabbage, allspice, mustard, horseradish, vinegar. Candidates are from the same food group and used in at least 100 recipes.
