Battered and Fried Oyster

I haven't battered and fried oyster for many many years, it is about time to fry a few now.  My batter is simple, just flour, cornstarch (equal amount), salt, baking powder, egg and water.  I remembered some really great ones I had when I was little at Lei Yue  Mun 鯉魚門, Hong Kong that was fried with scallion in the batter, so I added that too.  The oysters are first parboiled for a minute then dried.  Dusted with flour, they are then dipped into the thick pancake batter-like batter and then fried in very hot oil till golden brown.  Not bad at all.
