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
Cut peaches in halves and remove the stones.
Fill each half with sugar, mustard seed, celery seed, and horseradish.
Bind the peaches together with white string.
Make the syrup and pickle
In a pot, combine vinegar and sugar, then bring to a boil.
Pour the boiling mixture over the peaches in a jar.
Drain the syrup and boil it for 15 minutes each morning until thick.

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 softens and absorbs the sweet-sour pickling flavor.
- Vinegar
- Provides acidity that preserves the peaches and gives the pickle its sharp taste.
- Sugar
- Adds sweetness and, as the syrup reduces, thickens the pickling liquid.
- White mustard seed
- Contributes a sharp, pungent flavor to the peach filling.
The step that matters
Drain the syrup and boil it each morning until thick. Reboiling the syrup over several days concentrates the sugar and vinegar, so it thickens and keeps the peaches preserved. Boiling too briefly or skipping days leaves it thin and less stable.

Fit is the average pairing score against sugar, mustard, celery, horseradish, vinegar. Candidates are from the same food group and used in at least 100 recipes.
