Cut the pork shoulder into 2" pieces. Cut the back fat into small pieces and grind it all together using a meat grinder with a ¼" plate. Set aside.
Mix all of the spices together in a small bowl. Then, add the mixed spices to the ground pork along with the water. Use a gloved hand to gently mix it all together. Be careful to not squeeze the meat as that will change the texture of the breakfast sausage.
Place a scoop (#16) of the mixture onto a piece of parchment paper. Cover with another piece of parchment paper and flatten into a patty using a burger press or heavy pan.
Place the formed breakfast sausage patties on a cookie sheet lined with parchment paper then place the entire tray into your freezer for two hours until the patties are frozen. Transfer the patties to freezer or FoodSaver bags and keep in the freezer.
Cook frozen breakfast sausage patties over medium heat until done (165°F).
