I want to can and sell my chili. I want it to have a good shelf life. I don't know whether to freeze it or can it. To can it, don't I need to put vinegar or BHT or some type of preservative in it? If so, 1.how much and 2.will I need to get it pH tested? I'm using 16oz and 32oz jars.
Thank you in advance.
