Native Americans didn't have refrigeration unless it was winter time. This was overcome by preserving meat in this fashion. This is one method to making pemmican. Another method is the same, except grinding the meat into dust add dried fruits and/or wild onion and then pouring tallow over the top. Then using an axe to chop off what you wanted to eat. It was eaten straight up or boiled in its own tallow. This is the simpler method. When they used berries it really became the perfect superfood. The berries were are high in vitamins c and other nutrients. This would prevent scurvy. If kept dry and sealed in tallow, it could last 50 years they estimate. The berries to use is called Buffalo berries. #mycookbook
