how to sterilize glass jars for jams and canning

Sterilising your jars is a vital process when it comes to preserving fruits and vegetables. If the jars are not properly cleaned, then your hard work trying to preserve the summers yield will be spoilt due to build ups of harmful bacteria.

If you are using jars with rubber seals, remove them before placing them in the oven.

Method:

  1. Preheat your oven to 160˚C.
  2. Wash the jars and lids with hot soapy water and rinse them thoroughly BUT DON’T DRY.
  3. Place the jars on a baking tray and put them in the oven for 10-15 minutes.
  4. Soak the lids and rubber seals in boiling water whilst the jars are in the oven.
  5. After this time, with caution and thick oven gloves, remove the jars from the oven and set them aside, ready for immediate use.
  6. Remove the lids and seals from the hot water and leave them to drain. Once again, DO NOT DRY THEM BY HAND.

I use this method for sterilizing my jam jars EVERY TIME and I haven’t had any issues with contamination at all. You can use this method of sterilizing for most jams and canning when it comes to preserving the abundance of summer. This method does however, depend on the types of jars that you’re using – this method is written for the sterilization of regular twist-top jam jars with a ‘pop’ seal.
