So, currently we eat out of freezer bags, rehydrating meals I've packaged up at home from dehydrated ingredients. Lately, we've been camping a lot above tree-line, and thus have been using a bear cannister because hanging a bear bag isn't feasible.
When the food is rehydrated, it uses only about half of the quart-sized freezer bag. There's a lot of room taken up by excessive freezer bag in the bear cannister. Then, there's a lot of waste packaging in the garbage as well.
I'd like to package ingredients in vaccuum-packs, using only the amount of material necessary to contain the dry ingredients, then use a Ziploc screw-top container, or something similar, to rehydrate ingredients. This would mean 2 containers, and probably 2 Reflectix cozies as well. My boyfriend disagrees with changing, because he doesn't want to have to wash the bowls afterwards, nor carry the "bulk" of the eating vessels, or try to put them in the bear cannister. He says it will also add to how much water we have to filter, to have clean water to wash utensils with. We don't eat out of one pot for the same reason, don't want to do the dishes. We just lick our spoons as clean as we can, drop them in our freezer-bag cozies, then drop the cozies in the bear cannister.
Are there other bags that are smaller than the quart-sized Ziplocs, but still handle boiling water, and still seal up?
For those that use the hard-sided container to rehydrate, how do you clean it afterwards? Do you carry a separate drinking vessel so you can have tea/coffee with a meal? Do you have favorite vessels that stack? I saw a gelato container with a screw lid that might be lighter than the Ziploc container–awww, I'd have to eat ice cream!
