I have this pot. It's great. I protect mine by keeping it inside a DYU cozy I made out of a reflective material (similar to those car windshield sun protectors). I put dehydrated food in the pot, add the hot water, put the lid one and nest the pot inside the cozy, 10 minutes later the food is nice and soft, still hot, but ready to eat.
Yeah, been doing it for several years now. It’s my fave kind of food for backpacking. You get yourself an inexpensive dehydrator and start experimenting. The key is in the sauces. Dehydration steals some of the food flavor, so you compensate by either making the sauces more concentrated, or by adding them later at the time of eating. There are some great YT channels doing dehydration.
