Why it works: Horseradish and mustard 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 Mango
Ingredients
Directions
Prepare
Soak the peaches in a mixture of coarse sea salt and water for two days.
Remove the peaches, wipe them dry, and take out the stones.
Fill and tie
Fill the peaches with minced garlic, horseradish, bruised mustard seed, sliced ginger root, celery seed, and onion.
Tie the peaches with thread and sprinkle with cloves, broken cinnamon, and turmeric.

Pour the seasoned vinegar over the peaches and store the jar in a cool place for three months.
Optionally, add oil to the filling.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peaches
- Form the body of the pickle, absorbing the salt, spices and vinegar as they cure.
- Coarse sea salt
- Draws moisture out of the peaches during the initial soak, firming the fruit.
- Cold vinegar
- Provides the acidity that preserves the fruit and gives the pickle its sharp flavour.
- Sugar
- Balances the sharpness of the vinegar with sweetness.
- Made mustard
- Adds pungency and sharpness to the seasoned vinegar.
The step that matters
Soaking the peaches in salt water for two days. Salt draws water out of the fruit by osmosis, firming the flesh and seasoning it before pickling. Too short a soak leaves the peaches soft and under-seasoned, while the salt level and timing together control how well the fruit keeps.
