Looks like a great fill, probably perfect texture.
Yea, bit of heaven there. The skin is really nice when smoked - snap is perfect. These couldn't have turned out any better. Note that I ground the meat one night, stuffed the next, smoked the next, ate the next. Altogether it's a fair sized job, but split up like that it was nothing.
BTW, that pork was $2 / lb. Super cheap sausages when you get find pork shoulder on sale.
