Ingredients
Directions
Prepare the peaches
Wash and wipe the peaches, then cut them in half.
Fill the peach halves with grated horseradish, mace, cinnamon, cloves, and white mustard seeds.
Place the filled peaches into a jar.
Make the syrup and finish
In a pot, boil together 1 pound of sugar and 3 pints of vinegar with the same spices.
Once the mixture is cool, pour it over the peaches in the jar.

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 becomes tender and sweet-tart as it sits in the spiced vinegar.
- Sugar
- Adds sweetness that balances the sharpness of the vinegar.
- Vinegar
- Acts as the preserving liquid, adding acidity that keeps the fruit tangy.
The step that matters
Let the syrup cool before pouring it over the peaches. Pouring boiling liquid onto fruit can soften it unevenly and cause it to cook rather than steep. Cooling the mixture first lets the peaches hold their shape while they absorb the flavour.
Swap the mace
How well each one fits the dish's main ingredients (peach, horseradish, cinnamon, clove, mustard, sugar, vinegar):
- Allspicefits better
- Nutmegfits better
- Cardamomfits better
- Macethe original
Fit is the average pairing score against peach, horseradish, cinnamon, clove, mustard, sugar, vinegar. Candidates are from the same food group and used in at least 100 recipes.
