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 ↓
Peach Mangoes
Ingredients
Directions
Prepare the peaches
Select moderate-sized, unripe peaches and wipe them clean.
Soak the peaches in brine for three days, then drain on a sieve.
Make the pickling liquor
Boil 1 quart of vinegar with 2 ounces each of whole white pepper and ginger, a blade of mace, 1 teaspoon of salt, ¼ teaspoon of cayenne, and 4 ounces of mustard seed.
Pour the boiling mixture over the peaches.
Fill and pickle
Cut a round from the stalk end of each peach and fill with fresh mustard seed, grated horseradish, garlic, and chopped shallot.
Replace the cut-out pieces and secure with thread.
After two months, the peaches are ready to eat.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peaches
- Provide the fruit that is pickled and becomes tender and flavourful as it steeps.
- Vinegar
- Acidity that preserves the peaches and gives the pickle its sharp tang.
- Mustard seed
- Adds pungent, sharp flavour to both the pickling liquor and the filling.
- Grated horseradish
- Contributes sharp, pungent heat to the filling inside each peach.
The step that matters
Securing the peaches after filling. Peaches must be filled and the cut-out rounds replaced firmly so the filling stays inside and the fruit stays submerged and sealed in the brine. Exposed fruit can spoil.
Swap the white pepper
How well each one fits the dish's main ingredients (peach, vinegar, ginger, mace, mustard, horseradish, garlic):
- Allspicefits better
- Clovefits better
- Turmericfits better
- White pepperthe original
Fit is the average pairing score against peach, vinegar, ginger, mace, mustard, horseradish, garlic. Candidates are from the same food group and used in at least 100 recipes.
