We're hoping to try something different for an expedition this year. We're trying not to bring any prepackaged dehydrated stuff, get fresh ingredients at home, pre-plan and pack our own meals, dehydrate a bunch of stuff ourselves, etc. Hoping it will save us a ton not only economically, but on packaging, weight and waste.

Ideally, we could package all that up at home then either ship it early or load it into a carry on to bring down to Argentina with us. But I have no idea about getting stuff like that through customs, etc. Does anyone have any experience with it or suggestions?
