1. Peel and devein (or thaw) shrimp; remove tails if you like. In a bowl, combine egg white, 1 tablespoon cornstarch, and salt. Pour over shrimp, stir, and refrigerate 1 hour.
2. Drain the pineapple; reserve 2 tablespoons of juice, and place chunks in a bowl. In a separate bowl, combine reserved juice, water, sugar, remaining tablespoon of cornstarch, ketchup, and cider vinegar. Stir well.
3. Remove shrimp from egg-white mixture; drain well. Heat oil in a wok or heavy skillet over medium-high heat. Add shrimp and stir-fry 2 minutes, or until pink. Add ketchup mixture and peas; cook 2 to 3 minutes, until sauce is thickened and bubbly. Stir in pineapple. Serve hot over rice.
