Step 1

Whisk broth, sherry, tamari (or soy sauce), chile-garlic sauce and cornstarch in a small bowl. Set next to the stove.

Step 2

Heat a 14-inch flat-bottomed wok or 12-inch skillet over high heat until a bead of water vaporizes within 1 to 2 seconds of contact. Swirl in 1 tablespoon oil, then add garlic and ginger and stir-fry until fragrant, about 10 seconds. Push the mixture to the sides and carefully add shrimp, spreading evenly into one layer. Cook undisturbed for 1 minute. Then stir-fry the shrimp, incorporating the garlic and ginger, until the shrimp just begin to turn pink but are not cooked through, about 30 seconds.

Step 3

Swirl in the remaining 1 tablespoon oil. Add sugar snap peas and salt; stir-fry until just combined, about 30 seconds. Whisk the reserved broth mixture and swirl it into the pan. Stir-fry until the shrimp are just cooked and the sugar snaps are tender-crisp, 1 to 2 minutes. Sprinkle with scallions.
