I'm pretty new to casing up sausage, so maybe I'm overreacting here. But I just used some of my first batch of casing from Syracuse to make some brats... and I'm not overly pleased. There's some kind of weird stuff all over the outside of them, as you can see in the pics below. I don't see this in other people's pics (long time lurker here), nor do I see this on sausage I have bought from butchers. I have used Home Pak and didn't have any of this problem, but those had other problems so I wanted to try something 'better'... is this normal??? Should I complain? Can I eat this?
