Notes
Expert Tips:
- Plum varieties: Red or black plums have all worked well for me. Each will give a slightly different flavor and color. No need to peel!
- Sugar adjustment: Start with less sugar and add more after cooking if needed, depending on plum sweetness.
- Storage: Refrigerate up to 3 weeks, freeze up to 6 months, or process in a water bath canner for long-term storage.
