"This was an experiment, and it turned out well! I only used cellulose casings and that was spot on, I am not a fan of hot dogs with a skin. These can be all beef, all pork, or a combination. For this first experiment, I will be making them as listed here, which is a combo of beef and pork. No food processor will be used, just ample use of my electric grinder and a mortar and pestle. Keeping the grinder and meats cold is essential. I used collagen casings which are removed after simmering in water. Feel free to use casings of your choice...."
