How to sterilise jars in the oven
Learn how to sterilise jars in the oven ready to store homemade preserves including jams, marmalades, chutneys, compotes and fermented vegetables.
Materials
- Glass jars with lids
Instructions
- Check the jars and lids are in a good condition. Do not use any lids which are damaged or corroded.
- Soak the jars in warm water to remove any labels.
- Wash the jars and lids in hot soapy water and dry using clean kitchen paper. Pay extra attention to the thread at the top of the jars where remnants of food can easily collect. Alternatively, clean the jars and lids in a dishwasher on a hot setting.
- Place the jars and lids separately on a baking tray. Put in the oven at a low setting (140oC, 275oF, gas mark 1) for 10 to 15 minutes. If any jars/lids have rubber seals remove these and do not put them in the oven.
- Fill the sterilised with your homemade jam, marmalade or chutney while the jars are hot and then fit the lids.
- Leave to cool and then add labels if needed.
