How to Make It
In a small bowl, combine 1/2 cup low-sodium chicken broth or water, 1 tablespoon dry white wine, 1 tablespoon soy sauce, 1 teaspoon sugar, 1 teaspoon toasted sesame oil, 1/2 teaspoon kosher salt, and 1 teaspoon cornstarch, stirring until the cornstarch dissolves.
Place a wok or skillet over medium-high heat. Add 1 tablespoon olive oil and heat for 30 seconds. Add 2 tablespoons minced scallions (white parts only) and 1 1/2 tablespoons grated fresh ginger and stir-fry until fragrant, about 15 seconds.
Add the cornstarch mixture and bring to a boil. Cook, stirring constantly to prevent lumps, untils the sauce thickens slightly, about 1 1/2 minutes. Pour into a bowl.
