Pork and Napa cabbage dumpling stuffing

• 1 lb ground pork
• 4 cups/1 lb diced Napa cabbage
• 1 bunch (5-7 pieces ) scallion chopped
• 1 tbsp cooking wine
• 1 tbsp vegetable oil
• 1 tbsp soy sauce
• 1 tsp sesame oil
• 1 tsp salt
• ⅓ tsp white pepper powder
• ½ tsp onion powder

Mix all ingredients together well. It is best to mix them in circular motion (toward same direction) for at least 15 times. That tenderizes ground pork during the mixing.
