Processing Timetable

At the end of the cooking time, have ready a clean, dry wooden board, a pair of tongs or oven mitts for removing the jars from the oven, and the clean tops complete with clips, screw tops and rubber rings—whatever is needed for your particular jars. Lift out the jars one at a time. Have ready also a saucepan of boiling sugar syrup, or a kettle of boiling water. Fill each jar to overflowing. Put the rings, tops and screws on, tighten as much as possible. As the jars cool, tighten the screwbands every hour or so, until quite cold. Leave to stand for 24 hours.
