I was cutting up a deer the other day and was having a difficult time getting the backstrap sinue off. I was going to post on here to find any hints. Before I had time to get on the computer I wanted to freezer pack the deer up. Recently I started par-freezing my deer prior to vacuum sealing it up. I find it easier to seal, this way the sealer doesn't suck all the juice out of the meat. Anyway back to the subject, I started cutting the back strap up into portions. When I made my cut I started from the side opposite to the sinue. I left just a little bit uncut at the sinue side, bent the strap in half and the sinue peeled right off. I think the key to this is that the backstrap wasn't completely frozen just til the meat was firm not a solid brick.
Anyone else have any other hints at removing the sinue? Hope this helps anyone getting started.
