Preparation:
Ginger should be 1 inch long, peeled and minced. Green onions should be trimmed and thinly sliced. Slit the shrimp up the back with a sharp knife and remove the vein. Do not shell the shrimp. Heat the oil in a wok or wide heavy skillet. When the oil is rippling, throw in the shrimp and stir-fry over high heat for 2 minutes. Drain very well. Return 1/2 T oil to the wok. Heat. Throw in the shrimp along with the ginger, garlic, and onions. Stir-fry for 20 seconds. Season with salt and freshly ground pepper. Stir-fry for an additional 20 seconds. Serve at once.
