Alternative to freezer bag cooking?

[Charlie Vee 1961]

Hey fellow travelers! I watched an interesting YouTube where a hiker was extolling the virtues of his travel mug for rehydrating his dehydrated food. He remarked that a travel mug was kind of narrow and required a long handled spoon. I did a bit of research and found a Thermos brand stainless steel food storage container (20 oz.) that I later purchased at  Target store for just under$20. The idea is that certain elements of the plastic can leach out when boiling water is poured into the plastic freezer bag. I know it's another piece of gear to carry but the idea certainly got my attention.  Any opinions on this? BTW - the YouTube in question was titled "freezer bag cooking sucks" or something similar.  I hope this is of some use to someone.  Regards,  Charlie.

Hey Charlie, I do use freezer bags for some rehydration (often cold) and on occasion for some hot, but not quite boiling rehydration. However, my primary rehydration / cooking method (unless it’s a freeze dried meal in the package, which is fairly often), would be in the cookpot that I’m already carrying.

I guess the idea is to free up your pot to boil water for a hot drink or something like that. I see your wisdom in rehydrating in the pot - less to carry. I'm just wondering if it gives you a bit more flexibility, ie maybe have a hot cup of soup while you're waiting on your main. Or getting your wash up water heated or similar.  I will trail test this and report back. Unsure of the weight addition with the extra container.

just rolling up a potato in aluminum foil, and tossing it into a campfire embers, goes a really long way to satisfying your stomach!  just keep rotating it so it does not burn on one side
