I'm not a canner, but am interested in doing it -- I just thought sugar was a preservative and maybe necessary. We don't go through a lot of food around here, so sometimes things go bad even refrigerated.

I usually have a lot of garden tomatoes, but I've been roasting and freezing -- I would love to can the roasted tomatoes (on the grill with garlic and basil) and give away as gifts. Is this possible without sugar? I'm also thinking of making salsa without sugar and canning that.

I'd prefer not to kill any of my friends and relatives off, if I can help it

Thx
