Jayzus Bruce ya fergot ta tell im about cutting the head fer later..trymyluck, you did it the right way n hopefully you squeezed a coupla cloves of garlic each side of the fish prior to wrapping in foil..
Only thing i woulda done different is cut the head n flaps off and leave for Fishead Soup(Pssarosoupa)..
Dont know what ya missing till you try especially with big Reds...
Cheers
