@Diane: Tubers are totally paleo, albeit regular potato isn't that great. Any other root is great- sweet potatoes, yams, beats etc. Quinoa, i read, has some toxins that could cause problems like leaky gut syndrome etc. Check the internets for more information ;)
This is what i used to make (traditional) pemmican, it's written simple and effective:
Meat has to be very lean before drying, i used <5% fat grassfed fine ground beef. I got wild blueberries in our local farmers market. After drying they were sublime, so good, nothing on market comes close, the worst are freeze dried berries. I used the same amount of dried wild berries and dried meat and just enough tallow to keep it together, which actually was quite more than what i anticipated. I also added just a little of salt at that time, the article talks about it. I'll make some pictures next time i'm doing it.
If youre making tallow, it's actually quite simple. Get some grassfed suet, kidney fat. I freeze it so i can cut it easier. I get about 10lbs and cut it first in 1 inch slices and then in 1" cubes. I then put it all in a turkey roasting pan and put it in the oven on about 215 degrees. Fat should never smoke! Mix the fat few times. I let if "roast" for about 8 hours and then use a soup spoon to pour and force it through a sifter into glass jars that i put in a fridge to cool off. There shouldnt be any debris, just clear jellowish liquid. The more debris the shorter the lifespan. I freeze it but i don't think it's necessary. I use it for all my cooking. You will have to heat it up before using for pemmican, just don't go over 200...
Hope that helps!
