I also love canning. I've got a "summer kitchen" that is now in the corner of the building with my long arm (summer kitchen was there first LOL!)
I do both water bath and pressure canning, so I put all sorts of food. My DH has a reaction to sufites and they are commonly added as a preservative to a lot of store bought foods.
I prefer corn frozen, but love canned green beans. I also can fruit in very light syrup, and then I can dump a few jars worth into a pan, and a crisp topping and have a yummy desert in short order.
