In a small bowl, combine the shrimp, cornstarch and 2 teaspoons of the orange juice. Toss to coat and set aside.
Whisk the remaining 1/3 cup orange juice, sherry and sriracha together in a small bowl and set aside.
Heat the vegetable oil in a wok or large skillet over high heat. Add the ginger and stir-fry until fragrant, 30 seconds. Add the shrimp and stir fry just long enough for the shrimp to turn opaque on the outside, about 1 minute.
Add the snap peas, stir fry an additional 30 seconds, then add the orange juice mixture and dried orange peel. Continue cooking just long enough for the sauce to thicken, 1/2 to 1 minute. Stir in the scallions and remove from the heat.
Serve over steamed white rice.
Notes
About the orange peel:
Although you can substitute orange zest for the dried orange peel in this dish, the dried version adds a depth of flavor that you can't quite duplicate with fresh zest.Drying the peels concentrates the flavorful oils they contain, while the process of zesting releases a good deal of those oils into the air. Both versions have their place - it just depends on what you're making.You can make your own dried orange peel in advance and store it in the refrigerator for up to 3 months so you always have it on hand for stir-fries and sauces.
