Why is the braised hairtail in the hotel so fragrant and delicious?

The problems in practice are as follows

Before making delicious braised hairtail, we should first prepare ingredients, including hairtail, flour, coriander, ginger, onion, star anise, pepper and garlic. When the ingredients are ready, cut the onion, ginger and garlic into powder and put them in a clean bowl. Then cut the hairtail into small pieces, wash it with a flower knife and put it in a clean plate for later use.

At this time, you can heat the pot, pour the right amount of cooking oil into the pot and boil it. After the oil temperature comes up, dip the prepared hairtail section in flour and fry it in the oil pan. When the hairtail section is fried until golden on both sides, pour the excess oil into the plate. At this time, you can add clean star anise, pepper, onion, ginger, garlic, white vinegar, cooking wine, soy sauce, white sugar and clear water (clear water, as long as you don't bring fish), then add a proper amount of edible salt and stir well, then cover the pot and boil. When the water boils, reduce the heat to collect the juice. Sprinkle chopped green onion after cooking, and the delicious braised hairtail is finished.

Tip: When frying hairtail in the pan, you must touch the flour, so that the fried hairtail will appear golden yellow.
