For the avid home Cook nothing compares to natural hog castings for your homemade sausages. We are one of the only places in Hong Kong where these are available.
This is purchased as a "bundle" and approximately 90M in length and diameter of 26/28mm.
The casings are salted and can be frozen for future use. Just soak in cold water previous to using.
With plastic tubing for easier transfer to sausage piping nozzles.
