What we really need to talk about when we are talking about pork and the wonderful pork fat is pigs. Unfortunately, the pork industry took it upon themselves about twenty years ago to "lean up" the typical domestic pig. They say it was driven by customer demand, but I feel it was driven by the fact that for the most part they can sell lean alot easier that they can sell fat. All that said and done the hog one typically eats today is so lean it is hard to eat. Smithfield has taken it one misguided step furhter and sells a product called Lean Generation! One can not make sausage that is properly laced with the all important fat if it aint there! Leave it to the ever resourceful minds of ex-hippiest solve this problem. About twenty five years ago a guy named Bill Nima had the bright idea to raise animals the way god intended them to be raised, you know outside in the fresh air, eating things they might find naturally around them. Niman Ranch, twenty five years later produces an excellent product, includeing pork, lamb and beef. It is exspensive but worth it. The pork is excellent. The loin eye is marbled. the animal actually has back fat!! A sholder from Nian or any other "natural" producer is going to have the fat that you are looking for. I am in the wholesale meat industry an sell NIman meats. The quailty is there. You can find it retail at any Wholefoods market, EarthFare market and other natural type retailers. If not you can buy it from them direct, but you will pay
