In a large bowl, combine the bean sprouts, shrimp, eggs, green onions, and garlic powder, mixing thoroughly to ensure everything is evenly distributed. This step sets the stage for a well-balanced and flavorful egg mixture.
Heat oil in a skillet over medium heat and pour in approximately ½ cup of the egg mixture to form a patty. Continue adding more patties to the skillet, working in batches. Cook each patty for about 4 minutes per side or until they turn golden brown and crispy. This ensures each patty is perfectly cooked with a golden, delicious exterior.
Prepare the sauce by combining chicken broth, cornstarch, sugar, cooking wine, and soy sauce in a saucepan. Whisk the mixture together and cook over medium-low heat, allowing it to simmer until it thickens, which should take about 5 minutes. This step creates a rich, glossy sauce to enhance the dish.
Drizzle the sauce generously over the patties, letting it coat each one for added flavor and a glossy finish. This step enhances the dish with a rich, savory layer that ties all the flavors together.
