It is recommended to sterilise glass jars or bottles that you are planning to use for preserves and fermenting foods. This is done to prevent bacteria and mould from forming. As I am planning on fermenting coconut milk to make coconut yoghurt, I figured it’d be helpful for myself and anyone else to put together a simple step by step post on sterilising glass jars.
Wash the jar in hot, soapy water then rinse under hot water
Place the jars in a large pot of boiling water for 10minutes
Remove the jars from the pot and place them upside down on a clean tea towel to drain
Place the jars on an oven tray in an oven set to 150 degrees Celsius for about 20 minutes or until the jars are dry
And there you have it. Nice, clean, Sterilised jars.
Note: hot mixture can go into hot jars and cold mixture in to cold jars, so the jars will need to be left to cool down before making the yoghurt.
