I've only been able to find dehydrated milk around here in large packages (~5Lb), nothing that seems like it'd be appropriate to carry while hiking.
For people that use it, how easy is it to find on the trail? How do you manage the portions of it?
I don't know if I'll use it or not, but if I grab Carnation Instant Breakfast packets, it'll be nice instead of just plain water, or maybe make warm and mix in some granola for a nice breakfast. Or just mix with whatever for a nutritional boost.
