Good question and I would like to hear what others have to say. I always put 3-5 deer in the freezer each year and here is what I do:
Have about 12 logs of summer sausage made. I don't really like it but I give it as gifts, have it out as holidays, etc.
I cut the tenderloins out (inside the rib cage) when I am field dressing and eat them day of.
The rest is ground up except for backstraps. I really enjoy burgers, chili, meatloaf, goulash, etc. made out of the ground meat.
