Quick Answer
Natural casings can be used for making snack sticks, but they may require special handling and equipment to prevent bursting during the stuffing process.
Choosing the Right Casing
When selecting natural casings for snack sticks, look for hog middles or sheep casings that are specifically designed for summer sausage or snack sticks production. These casings are typically thinner and more prone to bursting than traditional hog casings used for larger sausages. You can often find these casings at specialty butcher supply stores or online.
Stuffing and Linking
To prevent bursting, it’s essential to stuff the casings slowly and evenly, using a casing attachment on your sausage stuffer. Aim for a stuffing pressure of around 30-40 psi, and make sure the casings are cooled to around 40°F (4°C) before stuffing. Once stuffed, twist the casings into 4-6 inch lengths, depending on the desired snack stick size. Use a sharp knife or sausage twister to seal the ends of the links.
Seasoning and Drying
To ensure your snack sticks develop a good flavor and texture, use a seasoning blend specifically designed for summer sausage or snack sticks. Aim for a fat ratio of around 30-35% to prevent excessive moisture buildup and promote even drying. After stuffing and linking, hang the snack sticks in a temperature-controlled environment with good air circulation, aiming for a temperature of around 70-80°F (21-27°C) and a relative humidity of around 50-60%. Allow the snack sticks to dry for at least 24-48 hours before slicing and packaging.
