First, grind 2 lb of pork loin using a food grinder. Run it through the food grinder twice for the smoothest texture. Add the ground pork loin to a bowl.
Add 1 tsp of garlic powder, ½ tsp of white pepper, 2 tsp ground cinnamon, 5 tsp of granulated sugar, 2 tbsp of corn starch, ¼ cup of fish sauce, 1/2 tsp of salt, 2 tsp of baking powder, and ½ cup of ice water to the bowl. Mix until well combined.
Add the ground pork mixture to a Ziploc bag and freeze for 1 ½ hours. Flatten the ground pork so it's as thin as possible. This will help the pork reach the correct temperature faster.
Empty the ground pork into the bowl of a stand mixer. Make sure to save the Ziploc bag for later. Whip on speed 4 for 5 minutes. Increase the speed to 6 and whip for another 5 minutes. Transfer the ground pork back into the Ziploc bag and freeze for 40 minutes. Make sure to flatten the pork mixture.
After 40 minutes, empty the ground pork into the the stand mixer bowl, and whip on speed 6 for another 10 minutes.
Preheat the oven to 350 degrees F (177 degrees C).
Grease a 8x8 baking pan with neutral oil. Press the pork mixture into the baking sheet.
Bake for 40 minutes until brown on top.
Cool for 10 minutes in the pan and slice into strips for serving.
