1, remove the yarn from the back of the prawn, remove the head (the head of the prawn can be fried), and marinate it with cooking wine and ginger for a while.
2. Take the oil pan (you can fry the shrimp head first and then fry it with shrimp). When the oil is hot, turn on medium heat, add pepper and dried Chili, and take it out after it smells. Then add five or six slices of ginger, fry until dry, add sugar, stir with a frying spoon, then add a spoonful of watercress to fry red oil, and then pour in a little soy sauce.
3. Then add the shrimps to the fire. After the color changes, add onion and stir fry. Pour some balsamic vinegar 30 seconds before cooking.
