Directions
Prepare the peaches

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peaches
- Firm, unripe flesh holds its shape through the long pickling and absorbs the brine flavour.
- Vinegar
- Its acidity preserves the fruit and gives the pickle its sharp, tangy character.
- Mustard seed
- Adds a pungent, slightly bitter flavour that mellows during the long rest.
- Horseradish
- Contributes sharp, pungent heat that mellows as the peaches rest.
- Shallot
- Adds a mild sharpness and savoury aroma to the stuffing.
The step that matters
Soaking the peaches in brine. Salt draws water out of the fruit and firms its flesh, so a short soak leaves the peaches soft and watery in the jar. Soaking for the full three days lets the salt penetrate and firm the peaches before pickling.
Swap the white pepper
How well each one fits the dish's main ingredients (peach, egg, vinegar, ginger, mace, mustard, horseradish):
- Allspicefits better
- Cinnamonfits better
- Clovefits better
- White pepperthe original
Fit is the average pairing score against peach, egg, vinegar, ginger, mace, mustard, horseradish. Candidates are from the same food group and used in at least 100 recipes.
