2 cups all-purpose flour (300 g)

Instructions
Beef filling
Add beef, ginger, scallion, salt, sugar, Sichuan peppercorn powder and white pepper powder. Blend 10 seconds. Add egg, light soy sauce, sesame oil, Shaoxing wine and oyster sauce. Blend for another 10 seconds. Stir the filling by hand for minutes until sticky.
Spread large scallion white on top and then drizzle around 2 tablespoons of hot oil. Mix in chopped white onion. Mix well, cover and set in fridge. For beginners, I recommend set the filling until slightly hardened. The filling is for 2 batches, 20 pancakes. However the dough is for 10 pancakes each time. If you want to use all of the filling once, double the dough.
Dough
Add salt in all purpose flour and then add hot water firstly. Gently stir the hot water in. And stir in cold water too. Roughly knead to form a dough. No need to be smooth. Cover and set aside for 30 minutes.
Re-knead the dough, it should be smooth very quickly. Cut into 50g portions (10 pancakes from this batch) and then roll out to wrapper. Seal it completely. Avoid the edges meeting the filling, otherwise the sealing work is hard to complete.
Frying
Place the pancakes in a pan with oil, slightly press the center so the bottom can contact with the pan in better ways.
Heat until the side becomes crispy. Then turn over and fry the other side. Once the two side becomes well browned, slow down the fire and over with lid and let the pancake heat for another 3-5 minutes. This can further cook the inside part and make sure the inner part is well cooked too. Then remove the lid and heat both side for another 30 seconds separately until the surface turn crispy again.
Transfer to oil paper to remove extra oil and enjoy!! Meat pies are always a little bit salty, so make sure you match it with some light and healthy vegetable soup.
Notes
The Nutrition Facts is based on each single pancake.
The filling is for 20 pancakes, namely two batches. If you want to sue all of the filling, double the dough and make a 4 cups flour batch.
