Non-plastics storage suggestions
if you are planning on continuing to freeze, yet want to make single-serving portions, i would recommend a vacuum bag system, like this one, which is what i use: http://tinyurl.com/4ygotv9. it's a bit of an expense up front, but it will pay for itself in the long run easily. i now make batches of things, freeze them in portions, then seal them with this and they last AGES.

EDIT: i just realized that your question specified NON-plastic solutions, but i took it to mean you mean non-plastic storage containers. the bags used for these are quite food-safe, as far as i know. i apologize if it's not exactly what you are looking for. but it really works well, and avoids the dangers you read about with a canning solution.
