Never seen REAL pemmican for sale anywhere, but who knows??? As far as comparing/contrasting it with an MRE... personal choice counts for a lot, but you can put a lot more fat/protein/vitamins/minerals in the same space if you go with the pemmican. As far as flavor goes, they're both the same, some people love it (either one) while others can't choke it down to (literally) save their life.
