USE ONLY WIDE MOUTH PINT JARS
Bake jars for 10 minutes at 245 degrees on a cookie sheet. Do this just as the cheese is almost done. Jars must be hot when putting the cheese in.
There are two ways that you can melt the cheese.
First way- Melt cheese in pan, slowly. Put melted cheese in hot jars.
Second way- Melt about 3 cups of cheese in the microwave in glass bowl for 2-3 minutes. Stir cheese every minute or so to mix the cheese evenly until melted. Pour into hot jars. This way is much easier and less messy than doing it on the stove.
Process cheese in a water bath canner or a steam canner for 45 minutes.
