Remove the head of the hairtail, cut it from the head, remove the black film and internal organs inside, then rinse it and put it into the basin. Add onion, ginger slices, cooking wine and salt, repeatedly stir and marinate for half an hour to remove the fishy smell of hairtail. Prepare a plate, put starch in it, roll the pickled hairtail around it, shake it with chopsticks and remove excess floating powder. Put more oil in the oil pan, add hairtail when it is 50% hot, fry it slowly with a small fire, and turn it over several times with chopsticks to make it evenly heated. After the hairtail is fried to a yellowish color, it can be clipped out.
Leave a little base oil in the pot, stir-fry shallots, ginger and garlic, then add a spoonful of light soy sauce, half a spoonful of dark soy sauce, three spoonfuls of balsamic vinegar, three spoonfuls of tomato sauce and a handful of crystal sugar (white sugar can also be used, but crystal sugar will make hairtail brighter, and the color will be beautiful), simmer until the crystal sugar melts, pour hairtail, simmer for 20 minutes, thicken with a little water starch before taking out of the pot, and sprinkle. The ratio of sugar to vinegar can be adjusted according to personal taste.
Is your mouth watering? Try it quickly. Hairtail is wrapped in bright and ruddy sweet and sour juice, which is delicious and tasty. This is the best fish I have ever eaten. Finally, even the soup should be wiped clean with steamed bread. This meal is too satisfying.
