Well...I've got a bunch of deer scraps in the freezer, and a Cabela's gift card burning a hole in my pocket! I'm planning on using the gift card to get a meat grinder so I can make some deer burger and sausage. I've never ground any meat before, so I was wondering how much trimming I need to do to my scraps. Do I still need to try to get all the silver membrane and tendons off the pieces, or will the meat grinder chop it up enough so that it's not noticable? Any other advice from you meat grinding pros would be appreciated!
