- Remove stems: Use a toothpick or skewer to remove the stems from each plum.
- Dry completely: Pat dry with a clean kitchen towel. Moisture increases the risk of mold.
- Cut the plums: Make 3–4 shallow cuts around each plum to help the juice release more quickly and evenly.

- Seal and store: Close the lid and keep the jar in a cool, dark place. Avoid direct sunlight.
- Stir regularly: Every 2–3 days, gently stir with a wooden or silicone utensil (no metal!) or tilt the jar to redistribute sugar.
- Ferment for 90–100 days: After 5–7 days, syrup will begin to form. Continue fermenting for about 3 months.
- Strain and bottle: Once fully extracted, strain the syrup into clean bottles or jars. Discard or reuse the leftover plums if desired.
Notes
Tips:
- Use only firm, unripe green plums (usually available May–June).
- Make sure all tools and jars are sterilized and dry to prevent mold.
- If mold appears, discard the batch and try again — cleanliness is key!
- For easier stem removal, press a skewer into the edge of the stem and lift straight up.
Important!
- Avoid metal tools — the acidity of green plums can react with metal, which may affect the flavor and even damage your utensils.
- Stick with wood, silicone, or plastic for safe and clean fermentation.
- If you must use metal, wash it thoroughly right after use to prevent corrosion or off flavors.
