BUTTERLY THE SHRIMP, LEAVING THE SHELLS ON. Pass it through 2 inches or so of oil at 350 degrees. This means frying the shrimp for about 10 seconds. It is not fully cooked when you scoop it out of the oil. Drain and set aside. Make the sauce: Combine 1/3 cup catsup, 1 TBS. and 1 teaspoon of dry sherry, 1 TBS. and 1 teaspoon of sugar, and 1/4 teaspoon of salt. Set aside. Heat 2 TBS. of oil in a wok and bring the heat up so that the oil is shimmering. Stir fry scallions (cut on the diagonal in 1 inch pieces) and about 8 1 inch slices of fresh ginger. Then pour in the sauce and let it thicken. Next add the shrimp(s) to the wok and stir fry until done. Serve with white rice.
