How to cook hairtail stew at home is as follows:

1. Clean the hairtail and cut it into sections. Blot excess water from the fish with paper towels.

2. Use eggs and flour to make a thicker batter, and add a little salt in the batter. Coat the fish segments with batter.

3. Put the batter-coated fish segments into the frying pan and fry them with oil on both sides.

4. Because the fish has been cut with oil, in order to avoid excessive fat intake, lay onion segments, ginger slices, beaten garlic, Sichuan peppercorns, and aniseed on the bottom of the pot.

5. Place the fish pieces on top of the condiments, pour cooking wine, soy sauce, a little vinegar, sugar, a little salt, and add enough water. Bring to a simmer over high heat, then reduce to medium heat after the soup boils. Finally, collect the soup and plate it.
