- 
        
        Scale and gut the fish and
              clean it thoroughly.
 
        - 
        
        Score both sides of the
              fish diagonally down to the bone at intervals of about 6 mm.
 
        - 
        
        There are two reasons for
              doing this.
 
        - 
        
        Since the fish is to be
              cooked whole, it prevents the skin from bursting and it allows the
              heat to penetrate quickly and at the same time helps to diffuse
              the flavor of the seasoning and sauce.
 
        - 
        
        Heat up about 4 1/2 cups
              oil in a wok or deep-fryer.
 
        - 
        
        Fry the fish until golden.
 
        - 
        
        Take it out and drain.
 
        - 
        
        Leave about 1 tablespoon
              oil in the wok, put in the finely chopped onions, ginger root and
              sugar.
 
        - 
        
        Stir to dissolve the
              sugar, then add the bean sauce followed by the rice wine or
              sherry, soy sauce, stock and the fish.
 
        - 
        
        Bring to the boil, then
              reduce the heat and cook until the juice is reduced by half.
 
        - 
        
        Turn the fish over and
              continue cooking until the juice is almost evaporated.
 
        - 
        
        Be careful not to break up
              the fish when lifting it out of the wok.
 
        - 
        
        It does not look right
              unless the fish is served whole with both head and tail intact.
