I have been using beef fat exclusively for my summer sausage and snack sticks and would have to do a batch with pork fat to compare. Please send me your meat to pork fat ratio for 12.5 lb and I can try a batch and see if I can see a difference . I will make 2 ea 12.5lb batches and compare. Personally I have never been able to tell the the difference between the meat I use, I have used Caribou,Whitetail and Sitka Black Tail Venison, Moose, Elk and Beef and can’t tell the difference in flavor of the finished product. I am planning on trying Black Bear this year with Extra Precautions to ensure it will be trichinosis free as our bears are well known to carry it.
