Made this for Valentine dinner, wow was it good! I used filet mignon, and instead of chopping the shrimp, I added prawns to the sauce and topped the steak with it. Cooked the steak on the grill instead of the oven broiler. Also added a "real" crab cake to the dinner, served with asparagus, sauted mushrooms and parslied potatoes. Delicious special meal, thanks for posting. My Valentine loved it!!
I used bay scallops for this dish instead of the shrimp, and omitted the scallions because no one will eat them. This smelled great while it was cooking. It is definitely a "must" to have all your little bowls of ingredients right beside you, because once this gets going, it goes quickly. I would also recommend using the Szechuan peppercorns instead of regular peppercorns if you can get them (I get mine from Penzey's); they add a nice little bite to the dish.
