Well i just started messing around with sausage and stuff. I have had some great results, my problem seems to be with casing seperation, i am using collegen casings. I have made some really good tasting beef sticks but the appearance is lacking due to the casing not being a part of the product. It can be peeled right off.
i am not doing this commecially, just for my own enjoyment. i stopped at a local meat place that makes these kinds of products and had tried their sticks and was talking with the guy behind the counter and ask him about this problem, he wasn't going to give up any secrets just told me i may want to look into adding more binder.
Moisture is not something I have had much of a problem with, i have had a batch of summer sausage turn out on the dry side. but akined it to the cut of meat that was used and the fact that I aded no pork to it for fat content.
I have tried some premade mixes as well as some of my own concoctions, some good some not so, but all was edible.
