I smoke small batches of summer sausage , and it usually turns out pretty good. I usuall get a premix seasoning add curing salt and smoke. This past winter i got seasonings from Waltons and smoked 20 lbs. And dint add anything else besides seasonings and cure salt, thats it. I had 4 logs of sausage in fridge after about 2-3 weeks in the fridge it had shrunk down to nothing , it was all shriveled up. What happened
