Some sausage casings can be twisted to create individual links, while others need to be tied. Twisting or tying is often a personal preference or is dictated by the type of sausage you are making. One of the many joys of making homemade sausage is that you alone determine the size of the sausage links you make. Tying a sausage casing is very simple and all you need is kitchen twine or string to complete the task.
Pre-cut the string into six-inch pieces. Plan on cutting at least 100 pieces of string; it will not hurt to have extra on hand when stuffing.
Plan on making two ties if you are creating individual links. By doing this, you will be able to cut between the two ties and keep the process simple.
Tie one end of the sausage casing in the same way you would tie a thread for sewing. Make a simple knot approximately 1/4 inch from the end of the casing.
Feed the casing onto the sausage stuffer. Stuff the casing to the desired length.
Tie the string around the casing, pulling it tight. A simple square knot will work fine.
Tie a second string 1/8 to 1/4 inch away from the first tie to create individual sausage links that can be separated after the stuffing process is complete. As before, a square knot will work well.
Continue to stuff the casing, tying the sausages off at the desired lengths. Leave approximately two inches of empty casing when you reach the end of the casing to tie the casing off securely.
Kitchen string can be used for natural or synthetic casings. If you plan to smoke the sausage, tie extra string to the ends of the casings to allow for hanging in the smoker. Square knots can be made easily by remembering the phrase, right over left and under, left over right and under.
