How to: Heat Process May 04 2018



Also called 'water bathing' or 'canning', this process uses heat to stop the growth of bacteria. It lengthens the shelf life and also ensures the jars or bottles are sealed correctly.


To heat process, get a large deep pot, such as a stock pot, and place a tea towel on the bottom. Place your jars on top of the tea towel, making sure not to cram them in and keeping clear of the sides of the pan. 

Fill up the pot enough to cover the jars. Bring to boiling point. Once the water is as boiling, you can begin your heat processing time.

Your jar lids should be convex when the processing time is up.  Carefully remove your jars and sit on the counter top to cool down overnight. By the morning your jars lids should be concave.
