When I have a garden, the last couple summers I haven't, I tried freezing zucchini to put in dishes in the winter time because they cost a buck or more in the winter here, it worked pretty well for the smaller ones but the larger ones didn't turn out so well. One thing I always regretted was not learning how to can. You would think I would have learned early on since when I was young canning was a big thing among the neighbor ladies, they'd all get together in one kitchen or another and form a assembly line around the table and can up stuff for their families.
