Make Pemmican is quite neat for those pretty long trips; when you are planning to go outdoors for months and need as much as non perishable food as you can afford. "Pemmican" is a concentrated mixture of animal fat and meat's protein used as a nutritious food. It is part of Canadian cuisine actually.
The ingredients used ase usually whatever was available + chunks of dehydrated meat; the meat was often bison, deer, elk, or moose. Fruits such as cranberries and saskatoon berries were sometimes added. Blueberries, cherries,chokeberries,
strawberries, chili, etc. You can add to the meat whatever you fancy.
The meat is cut in thin slices and dried, either over a slow fire or in the hot sun, until it was hard and brittle. (About five pounds of meat are required to make one pound of dried meat suitable for pemmican.) Then it was pounded into very small pieces, almost powder-like in consistency, using stones or a hammer. Then you can add mashed berries, potatoes,
herbs, whatever. The final result might be something that pretty much resembles a brownie
