This recipe came from the book Olympia Provisions, which I have modified in some of the processing and cooking methods.
3/4 tsp mustard powder
1 tsp chili powder
1 tsp sweet paprika
1 1/2 tsp ground white pepper
1 tsp ground coriander
3/4 tsp dried oregano
1 tbs chopped garlic
2 1/4 pounds pork shoulder
1 pound fatback
2 cups crushed ice
1 1/2 tbs fine sea salt
2 tsp sugar
1/2 tsp pink salt
1/4 cup milk powder, I used 1/2 cup because there was a grams/cup conversion discrepancy on the recipe
Sheep casing
Put your grinder parts in the fridge. Cube up the pork and fatback, and place it in the freezer on a cookie sheet until crunchy but not frozen solid. Using a mortar and pestle combine the garlic, mustard powder, chili powder,paprika, White pepper, coriander, and oregano to a paste.
Grind the meats with the course plate using half the crushed ice. Grind it a 2nd time with the course plate. The meat should stay below 39 degrees. Lay the ground meat on the cookie sheet, and freeze for another 30 minutes or so.
Grind the meat two more times through the small plate using the other half of the ice. Refreeze for another 20 minutes or so. Put the mixing bowl and paddle of your stand mixer on the fridge.
Add the meat, Spice paste, sugar, salt, pink salt, and milk powder to the mixing bowl. Mix on low for 2 minutes.
Place meat mix in chilled stuffer, and stuff into sheep casings. Twist into hot dog size links, and prick air pockets. Dry with paper towels, and hang overnight in fridge to cure and dry. Smoke as low as possible (around 150) until internal temp is 150. Immediately put in ice bath for 5 to 10 minutes. Dry off, and let sit uncovered on a wire rack in fridge overnight.
Re-heat and serve, or vac seal and freeze.
