Just finished making venison summer sausage using mostly backstrap with some pork fat. I know, why waste good backstrap for summer sausage. Around where I live deer are a real nuisance. The farmers are happy to get rid of them. Into the smoker and then after reaching temperature I put into the snow. Sausage turned out tasting Great. My casing are always like this. How do I keep my casing tight? Hope you like the pictures.
