How do I sterilize jars?
Sterilize in a water bath by placing the jars and lids in a large pot and covering with cold water. Bring to the boil and boil for 10 minutes. Remove from the boiling water with tongs and drain on a paper towel lined baking sheet. Any excess can be patted dry with paper towel. Alternatively place upright jars and lids in a preheated 250ºF/120ºC oven for 20 minutes.
