"Xiao Sun, cook whatever you want. I'm tired of the fish we usually cook at home, so it's a good time to change the taste. Do you have enough ingredients for this dish?"

"This dish doesn't require many ingredients. I saw some tomatoes nearby and thought of this method. It has a sweet and sour taste and is quite appetizing. And after removing the spines and slicing, it's safer to eat."

"Okay, okay, let's make this dish. Xiaoye, you can follow along and learn from us, so that when your family wants to eat it, they can make it themselves!"

Sun Aimin began to prepare the large snakehead fish. He first rinsed the fish's scales clean with water, then cut open its belly with scissors. As he did so, he explained to his nanny, Xiaoye, "Be careful not to damage the fish's gallbladder during this step, or the fish will taste bitter."

After opening the fish's belly, clean out the internal organs and remove the gills by hand. Rinse the blood off the fish's body and belly, then chop off the fish's head with a kitchen knife and set aside.

Next, it was time to fillet the fish. As he did so, he explained the technique: "When filleting the fish, keep the blade close to the bones, slightly tilted, and slice the fish neatly. Do the same for the next piece."

After shaving the meat from the bones of the two large pieces of fish, Sun Aimin carefully sliced ​​off the fish bones, and then began to slice the remaining fish meat thinly.

Cut the fish head in half and cut the bones into sections. Soak in water to remove any blood and rinse thoroughly for the fish soup. Add a little salt to the fish fillets and stir briefly, then rinse under running water to remove any remaining blood. The reddish flesh will now have turned pale, instantly enhancing its appearance.

He also added a little white vinegar to the fish fillets, added an appropriate amount of white pepper powder, and stirred it continuously, which could help remove the fishy smell and enhance the flavor.

"Xiao Ye, look, in this step, when stirring the fish fillets, you should stir them in one direction, gradually making them somewhat sticky. This will make it easier for the fish fillets to be coated with starch, and the taste will be better."

After completing this step, Sun Aimin poured the onion and ginger water that had been soaked in advance into the fish fillets and continued to stir and coat them with batter.

He asked Xiaoye to get an egg, beat the egg white into the fish fillets and stir again to fully blend the egg white and fish fillets, and then added cornstarch to make the cooked fish fillets smooth and tender.
