I really enjoy canning and preserving food. It is such a sense of accomplishment to take food and prepare it and put it in jars and can it. I used to think there was a science to all of it. I heard horror stories about botulism and other poisoning from my mother and Mrs. Macri, my junior high home-ec teacher, if it wasn't done right.
I follow recipes by the book. I give my jars a water bath or put them in the pressure cooker. So far... no deaths.
Whether it is pickling beans, making jam, or trying my own recipe for salsa, it is always rewarding. There is also something about canning jars that make good photos also.
