Reading edition
See directions for momentary dipping on page 117. This method can be used equally well on the empty casings. After the casings have a light orange color take them out of the solution and wash them well in hot water, cut and tie them.
After the Sausage has hung a week or two and is dry, hang it in the smoke house for a few days to give it a smoke flavor and it is ready for shipment. This will save a large shrinkage and the Sausage will have a better appearance. Sausage that has had the casing colored before being stuffed need not become rancid, as it is not exposed to the heat in a smoke house, which heat often causes the stearin and oil in the fat to separate, and as soon as this change takes place the sausage begins to become rancid.
