1. We need to prepare the required ingredients in advance to make this steamed tilapia. The main ingredients we need are ginger, cooking wine and onion. Of course, tilapia is an essential ingredient.

2. Wash the tilapia carefully and repeatedly, and then find a knife with the right size to scrape several holes on the tilapia. The depth of these mouths should be moderate, and both sides of tilapia's body should be cut, so that we can help tilapia taste better in the next pickling process.

3. Clean the shallots we prepared in advance and slice them, then cut the ginger into filaments. It is best to wash the cut fish with cooking wine, because it helps to remove the fishy smell. Next, we need to put the ginger and onion cut in the last step into the incision on the tilapia, and then sprinkle some salt on it. This is a pickling process.

4. Boil a pot of water, put a steaming curtain on the water, find an enthusiastic plate, put the fish being pickled on this plate, and then steam it on the steaming curtain. The specific time for steaming fish needs to be judged according to the size of the tilapia you make. You can take it out and eat it after steaming.
