Make sure your rack is on the bottom of the canner and place the jars in the water bath making sure that the water covers each of the jars by 1 to 2 inches. Add hot water to the canner if it doesn't measure up.
Cover the pot, turn up the heat under the canner, and wait for the water to start boiling. Once the water has come to a boil start your timer for 30 minutes.
When complete turn off the heat and remove the cover and let the jars sit for another few minutes.
Remove the jars and place them back on the dishtowel in a place where they will sit overnight to cool. Do not touch or move them till the following day.
