Ingredients
3 tablespoons finely grated fresh ginger
3 tablespoons soy sauce
1 tablespoon white-wine vinegar
2 teaspoons sugar
1 tablespoon cornstarch
Coarse salt and ground pepper
1 1/2 pounds peeled and deveined medium shrimp, tails removed
4 tablespoons vegetable oil
2 red bell peppers, seeds and ribs removed, cut into 1 1/2-inch pieces
8 scallions, cut into 2-inch pieces, white and green parts separated
Preparation
Press out ginger juice; whisk in soy sauce, vinegar, sugar, cornstarch, 1/4 teaspoon ground pepper, and 1 cup water; set sauce aside.
Season shrimp with salt and pepper. Heat 2 tablespoons oil in a large nonstick skillet over medium-high heat. Cook half the shrimp, turning once, until just opaque, 3 to 4 minutes; transfer to a plate. Add another tablespoon oil; repeat with remaining shrimp. Set shrimp aside.
Add remaining tablespoon oil to pan; cook bell peppers and white parts of scallions over medium-high heat, stirring, until crisp-tender, about 3 minutes.
Whisk reserved sauce; pour into pan, and bring to a boil. Cook, stirring, until thickened, 1 minute. Add shrimp and green parts of scallions; stir until coated with sauce, 30 seconds more. Serve immediately.
