Slice the pork into strips. Set aside.
Combine the potato starch and water, then let sit for 30 minutes.
The potato starch will be hydrated and set at the bottom of the bowl, and the excess water will seperate. Throw out the excess water.
The batter will have a clay consistency, crumble some of it on the sliced meat.
Using medium-high heat, heat the oil until it reaches 350F.
Add about 2 tablespoons of oil on the remaining batter so it becomes runny, then one by one pack each piece of meat with the runny batter, then place it directly into the oil.
Cook the pork for 2-3 minutes, and once they float, it indicates that they're done.
Remove them from the oil and let cool for a couple of minutes on a wire rack. Do little taps to separate each piece and to create airholes in the batter.
Increase the heat of the oil and once it reaches 375F, fry the pork again for 5-6 minutes. They should now turn golden brown.
