Pemmican is only going to be as good as its two ingredients, if you aren't using grass fed beef and beef fat, the flavor and quality difference is going to be pretty noticeable. Hint: check for mexican groceries and butchers, they know and like real meat, though of course, they also sell poor quality meats, so you have to find a butcher/store that stocks good meat. If you dry the meat at over 125, you are no longer really making pemmican, since the meat is cooked,, totally different flavor then. And if you render the fat at over 240, it gets a bad, sort of burned taste.
I found on a recent trip that the pemmican started tasting better every day, I think that's because my body started to recognize what an amazing food/energy source it is.
When the Indians started to sell pemmican to the white trappers and other frontier type people who learned how amazing it was as traveling food, they discovered that euros have a sweet tooth, and couldn't really get the actual flavor. Indians loved the flavor from what I read, and often preferred pemmican to meat. Makes sense, has more fat thus more goodness.
To adapt their trade pemmican to euro sweet teeth, they added a bit of ground up dried berries to the mix. One problem with that should be obvious, you are introducing sugars into an organic compound that is going to get warm during the day every day. Bacteria love sugar.
to me the best solution is to solve the sweet tooth, not to sweeten the pemmican.
I didn't try using pemmican as a stock for meals because it's virtually impossible to clean off rendered beef fat from a pot with cold water, it's difficult enough as it is with hot sink water and soap. So I just eat it and lick my fingers, that seems to work well. I use olive oil in meals, 2 oz a day is 500 calories, 4 oz, 1000. That also is the absolutely best way to drop pack weight, forget cuben and all that stuff, just use real food and a lot of fat.
By the way, as I posted in another thread here, if you haven't tried real old world cured meats, like jamon serrano, lomo (from spain), or its slightly less tasty cousin prosciutto, as a topping for breads or other things, you really should give it a try. Runs around 25 a pound, give or take, here in the usa. Tip: avoid anything that comes presliced in plastic packages, that stuff tastes really bad. Has to be sliced off the whole piece in front of you or it's not so good.
I'd thought of doing that instead of the old salami standby, and it elevated my meal stops to small little peak events every single day.
