In a medium bowl, whisk the egg white with corn starch, sugar, salt and pepper until a paste forms.
Add the shrimp. Toss to coat. Set aside for 10 minutes to marinade.
In a small bowl combine the garlic and ginger. Set aside. Must use fresh garlic and ginger - powder will not work in this recipe.
Heat oil in a large, heavy skillet over high heat for 3 minutes. Must get to 350 degrees.
Add the shrimp and the white and light green scallion pieces. Stir to coat with oil.
Cook, stirring consistently until the shrimp are cooked through, about 1 minute more.
Season to taste with salt and pepper.
Transfer to large platter and serve with steamed rice.
