7-second fillet is to cut the fish into thin slices, not the name of the fish. Theoretically, all fish can be sliced, but not all fish are suitable for slicing, such as eel, loach and crucian carp. Cutting fish into fillets has many benefits, because it is very thin, so there will be no fishbone left, which is convenient for the elderly and children to use; Secondly, fish fillets are easy to cook. I have been to a memory meal for seven seconds, and the picked fish fillets only need to be boiled in hot pot for seven seconds. According to the staff of the seven-second memory meal fresh fish hot pot restaurant, there are many fish that are most suitable for slicing, but they only choose to use wealth fish. First, wealth fish itself has fewer thorns; Second, the wealth fish is very suitable for children and old people to enjoy, especially for patients after hand surgery and maternal rehabilitation, which has the effect of promoting wound healing; Third, it is relatively easy to slice the fish. It is not an easy task to cut the fish into pieces as thin as paper, which tests the chef's knife work.
