Re: Tips on cutting up a deer
John, you have some good replies there ... you obviously do a bit of this yourself! We process about 20 - 30 deer a year, not a huge quantity, but enough to keep us busy a few days!
As for aging ... we always feel this is a must! We do not have a cooler for the deer, but have sectioned off a portions of the stand-alone garage to keep the heat from getting there. We keep a thermometer on the wall and a meat thermometer in a hind quarter. Out goal is to get the hide off as quickly as we can so it will cool as quickly as possible. Depending on the temperature is how long we let it hang. Aging is really only the rotting of the meat. As the meat breaks down, or decays, it becomes more tender (and the "gamey taste" of the venison diminishes). Optimum aging is just before the meat turns green! YIKES! That is always too close for comfort. For us, normal temps for the building during deer season are around 40 degrees. This means the deer will hang about 7 days. A little warmer and the deer get cut up sooner. A little colder, and the deer hang longer. If it is going to freeze in the building, or get too warm, the deer get cut into chunks and put in the refrigerator.
As for the fat, we have found there are really 2 kinds of fat on a deer. There is the slimy, soft, "tallow" fat that when cold coats the roof of your mouth and make the venison eating experience yucky. And there is the hard, back/ribcage fat that actually adds flavor and moisture to hamburg and roasts. We also like to run the hard fat through the grinder to keep the blades clean cutting. So, if the fat is soft and slimy, cut it off (we do this when skinning). If it is firm or hard, keep it. At least that is our approach. (BTW, the fat will be "stronger" or "gamier" in an older deer, especially an older buck).
