I've been wanting to have my own personal meal packages, things I've made for myself to my liking for long term use. The best comparison would be the entre items in MRE's. I would like to make up a large batch of something I like, then portion them out into containers and can them for long term storage. Jars seem smart, but their weight and potential for breakage are a concern for me. I've seen some people use mylar bags for long term food storage. I wonder if it's possible to process food in mylar the same way as jarred food. If anyone has had any experience with it and knows how to do it properly I'd love to hear about it.
