——[Door Nail Beef Patty]——
300g plain flour / 100g boiling water / 80g water / 3g baking soda / 200g beef / 80g water / 1/4 onion / 2 celery / 1 piece of ginger / half an egg white / 15g cornstarch / 1 gram pepper / 2 grams of five-spice powder / 10 grams of light soy sauce / 3 grams of salt / 2 grams of sugar / a little oil
—— [Here's how]——
1. Let's make the dough first, put the prepared flour into a bowl, divide the flour into two parts, blanch the dough with boiling water on one side, and mix the dough with cold water on the other hand, measure it a little, and mix the dough on both sides evenly
2. When it is not hot, add 8 grams of oil, knead the dough slightly, move it to the cutting board, beat it repeatedly until the dough is soft, cover it with a lid, and let it relax for 30 minutes
3. When the noodles are resting, process the filling again, cut the beef into minced pieces, put it in a bowl, pour an appropriate amount of water, add baking soda and stir well, and soak for 20 minutes (this step is mainly to make the beef more tender)
3. After soaking, pour out the blood water and drain it, the fishy smell of the beef is gone, only umami, add salt, grasp the viscosity with your hands, indicating that the collagen has coagulated, and then divide it into water many times, add a small amount many times, and add the next time after absorbing the water each time
4. Start seasoning again, add ginger (ginger can remove the smell and increase tenderness), add light soy sauce, sugar, pepper, five-spice powder, corn starch (corn starch can play a role in binding), and stir well again
5. Finally, add the onion and celery cut into small dices, be sure to pay attention, do not mix them well before wrapping, and then mix them when wrapping, mix too early, and the diced vegetables are easy to kill the juice
6. The dough is also relaxed, no need to knead the dough, the kneading dough is easy to get gluten, sprinkle some dry powder, directly put it on the board and knead it into long strips, divided into 12 small sections
7. Roll out a round dough that is thin around and thick in the middle, wrap the meat filling in the pie crust, seal it into the shape of a bun, and close it downward, is it particularly like a door nail? The raw embryo of the beef patty is ready
8. Put a little oil on the frying pan, put the finished door nail meatloaf into the pan in turn, put it next to each other, and fry it on low heat until the bottom is slightly yellow
9. Evenly brush a layer of water and oil on the surface of the patty, water and oil is a mixture of water and oil, 1 part oil, 5 parts water, use oil and water, in a half-fried and half-stewed state, to cook the cake
10. Cover the lid, simmer for about 45 seconds, open the lid, turn the meatloaf one by one, brush a layer of water on the surface of the meatloaf again, and the oil machine will simmer it, and the surface will be golden brown
