also, I just perused the pemmican manual before, But I believe I read that you should use the same kind of fat per the dried lean, does that mean you can't mix certain kinds of lean (say organs and muscle meat) in a single batch of pemmican, or more importantly, can one can't use pig suet with dried cow meat? I have a hard time getting grass-fed suet, but access to cheap pastured pork suet.
also does one need a grinder or can you just crush into small pieces?
