Background

This experiment, started on June 17, is a variation on traditional Korean cheong, which is typically made with unripe plum. This version uses unripe peaches, another type of stone fruit, to explore if they produce a similarly interesting syrup. The peaches were harvested from a backyard tree, providing a way to utilize fruit that might otherwise be eaten by deer before ripening.


Recipe

Ingredients

275 Unripe Peaches

275g Cane Sugar

Equipment

Mason Jar

Kitchen Scale

Instructions

  1. Preparation
    Wash the unripe peaches gently, remove the stems, and clear off any gum from the skin.

  2. Layering
    Add the peaches and most of the sugar (approx. 250 g) to the mason jar.

  3. Mixing
    Shake and tap the jar to distribute the sugar evenly and remove any air pockets.

  4. Topping
    Add the remaining sugar to the top, ensuring the peaches are completely covered.

  5. Sealing
    Seal the jar and store at room temperature.

Notes and Observations

  • The peaches used were small, about the size of a golf ball. Some had a dried, gum-like substance on the skin, likely from stink bugs.
  • The jar will be left at room temperature (approx. 70°F / 21°C).
  • The sugar is expected to draw moisture from the peaches via osmosis, slowly creating a syrup. This process will likely be slower than with more porous fruits like raspberries.
  • Due to their density, the peaches required a surprisingly large volume of sugar to achieve a 1:1 weight ratio.
  • The process will be monitored over the coming weeks, first for syrup formation and the dissolution of all sugar. Following that, we will monitor for signs of slight Lacto-Fermentation.
