Oh don't get me wrong, as a kid I thought it was the coolest thing extant, and as you say now, it's a fantastic snack and even addition to trail mix. I hadn't thought to rehydrate it, but I'll have to give that a whirl.I think that's one of those things that lost popularity with the space crowd and found use elsewhere. In this case, I believe it became pretty popular with troops stationed in tropical lands. More recently it's been popular among backpackers. You'll find freeze dried ice-cream in most any outdoor gear store. I like to take some along anytime I'm leading a trip with newbie backpackers. Freeze-dried ice cream + water + strawberries makes for a neat dessert after a long day of trudging through hills and woods.
@Physics girl phd: Nor should it, but Tang? Really?! I never could stand powdered drink mixes of any kind... yet I like slushies... clearly it's a matter of what we have as kids, and no virtue of taste. :rofl:
