What I started doing which is MUCH cheaper is I brought a dehydrator and dehydrate my own. I great frozen vegetables when they are on sale and they are all ready for the dehydrator then I vacuum seal them in canning jars! chocchipcookie has plenty of info on her Survival Mom site and there is a section in my Preparedness Manual on both dehydrating as well as vacuum canning.

Concerning dehydrating vs canning vs freezing. I’m considering which one I should apply more. Canning is great as long as there is heat during the winter. Freezing is great as long as there is power. I’m starting to see that storing dehydrated food might be the best bet in quite a few situations.
So I’m rather curious - I imagine you’re applying all three methods but are you likely to dehydrate first if feasible?
