Well not sure if this is right, seen a butcher do it. I take a torch and lightly braze it across the slimy stuff, stiffens it right up , then take a fillet knife and cut it off
That thread from a while ago that was posted was good
however i like to take off the silver on the back straps as I butcher. Then I take that silver and fillet off the meat, which is a thin strip. I put this in a quart bag and we make Philly steak sandwiches out of it. MMM good
I vacuum seal my stuff. grind the burger into the 1 and 2lb bags from Rural King , make my own summer sausage, breakfast sausage and brats.
Takes time, but I like knowing how my meat was handled. And I shoot quite a few deer a year, last year we got 11, 1 which I gave away. So 10 deer at 65 bucks plus adds up.
Don't worry, my first deer looked horrible, most of it went to hamburger as I had tore it all up
You'll get better
