Sterilizing glass jars

A guide to sterilizing glass jars and their lids for hot bottling preserves:


Give the jars and lids a good wash in hot, soapy water, rinse well, then dry. It pays to prepare more jars than you'll need.


Place the jars in a shallow roasting dish and pop them into a preheated oven, 120ºC; gas mark 1 for 30 minutes.


In a saucepan, cover the lids with boiling water, pop on a lid, then simmer them for 20 minutes or so. 


Take the tray from the oven and rest it on top of the cooker, then bottle the hot preserves immediately. Drain the lids and let them air dry for a moment before sealing the jars. Take care! Everything at this point is still very hot.
