A simple, small-batch plum jam recipe that requires no commercial pectin, perfect for beginners and made with just a few wholesome ingredients. This jam balances sweet and tart flavors with a rustic texture and natural thickness.
Do not skip the lemon juice as it activates natural pectin and helps the jam set. Stir frequently to prevent burning. Use the plate test to check jam set. For smoother jam, mash fruit gently during cooking. Jam can be cooked in a slow cooker on low for 2-3 hours as an alternative method. Store refrigerated and use within 3 weeks or freeze for up to 3 months.
