Prepare a big fish head and split it from the back, so that the fish sellers can help. Their tools are easier to use.
Prepare onion, ginger and garlic, mince ginger and cut onion into small pieces. Put more oil in the pot for frying fish heads.
When the oil is slightly hot, put the fish back down into the oil pan, and be safe! You can remove the black film, you are lazy. However, I'm not sensitive to the fishy smell, and my feeling doesn't affect it.
After the color changes slightly, turn over with a shovel and hands to continue frying the other side. Also fry until it changes color. Be careful and remember.
Then turn it over and add the onion, ginger and garlic. Add cooking wine. Don't be afraid of cooking wine, it's up to him to stink. Add boiling water, want boiling water! Add a little salt to taste and sprinkle some shallots. If you want to be fresher, have some monosodium glutamate.
