I have just recently started making my own snack sticks and summer sausage. I have been using casings but noticed the ones from the butcher were not in casings. I was told some butchers use a casing that is removed but not sure mine are that type. The reason I ask is I think I like them without casings and was going to do my first attempt without casings but was told they would not be presentable without the casings. Just looking for more info. Thanks.
