  1. Make sure that the probe is clean ahead of every reading to maintain accuracy and hygiene. Make sure that you clean it after each use. Clean it even if you are putting it in and out of the same jam repeatedly.
  2. Make sure that the reading has stabilised before settling on it. Some thermometers take some time to do this.
  3. Take the temperature from the centre of the jam pan. With probes or utensil-like thermometers, you can stir it through the mixture to get the most useful overall measurement.
  4. Avoid having the thermometer touch the bottom of the preserving pan. A reading at this hottest point will be a false reading.
  5. Know the setting point of the jam so that you can aim for this confidently. This is 105 degrees Celsius (220 degrees F).
  6. You should clean your thermometer according to the manufacturer’s instructions. Avoid scrubbing it too hard as some designs may result in the lines and numbers being rubbed off in time. If this happens, it will render the thermometer useless.
  7. Be careful when using the thermometer in boiling liquids so that you do not burn yourself.
