The key ingredient is rice flour. Add 1/2 cup of rice, 1/2 cup of sweet rice (sticky rice), 1~2 star anise, 1 tsp Sichuan pepper in the skillet, stir under medium power until rice is slightly yellowish in color. Let cool to room temperature and then grind with coffee grinder to obtain coarse flour powder. This rice flour can be preserved in a tightly capped bottle for quite a long period.
Slice 1 lb pork to 2~3 mm thick, rinse to remove blood, dry with paper towel. Marinate sliced pork for at least 2 hours in the fridge.
Evenly coat pork slices with prepared rice flour, place in a container. Then steam for 30 minutes.
If more spicy taste is preferred, drizzle cooked pork with chili oil. For decoration, sprinkle with finely chopped green onion.
