all i do is put the jars in the dish washer with very hot water. as they are being heated/sterilized, i put the lids and rings in a pan of water and bring almost to a boil. I bring the sauce to a boil as well and then hurry and pour into the jars. i put a lid and ring on and sung it down tight. I then invert the jar on its top for about 10 minutes and then bring it back to normal position and let cool. it will last like a year in the jar.
