Sweet and sour fillet of pork fancify

I used pork lean meat, 1, cut into coarse finger strips in a bowl, add a spoonful of cooking wine, a little salt, and pickle. 2. In an empty bowl, add two spoons of vinegar, three spoons of sugar and a little salt. Rinse the starch into water and pour it into a stirring bowl. Stir it evenly and use it as Scutellaria baicalensis. 3. In an empty bowl, add one egg white and two spoons of starch, a little white water, and make it pasty. 4. Mix the salted meat strips into the batter. 5. Pour the oil in the pan, heat the oil into the batter-wrapped meat strips, and place them with chopsticks. Suggest 6-7 pieces to be fried together, until the surface is white and salvaged, until all the meat is fried and served. 6. Pour the fried meat strips into the frying pan twice and fry until golden brown. 7. Leave a little oil in the pan, add tomato sauce (according to the number of meat strips) and stir-fry the red oil, pour in the sauce prepared in step 2, stir-fry until bubbling and sticky, pour into the fried meat strips and stir-fry continuously. The size of the fire depends on the situation, mainly in a non-paste pan, stir-fry for about half a minute.
