How to Make It
In a small bowl, combine chicken broth, wine, soy sauce, sugar, sesame oil, cornstarch, and 1/2 teaspoon kosher salt, stirring until the cornstarch dissolves.
Place a wok or skillet over medium-high heat. Add olive oil and heat for 30 seconds. Add scallions and ginger and stir-fry until fragrant, about 15 seconds.
Add the cornstarch mixture and bring to a boil. Cook, stirring constantly to prevent lumps, until the sauce thickens slightly, about 1 1/2 minutes. Pour into a bowl.
