In another forum someone asked if they could substitute butter for pork fat. Of course everyone said no including myself, but concluded that if could develop enough of a bind maybe it would work. Butter melts at 95°f and back fat at somewhere around 104°f which isn't a whole lot of difference.
Does anyone think with enough myosin development it could coat the fat well enough to hold together. or maybe make an emulsion with butter, soy protein isolate and water and add that to the lean pork mince.
I love a good challenge but I'm not sure if I want to go through the effort without some support.
