Step 1: Prepare the beef. Pat the sliced flank steak very dry with paper towels. In a medium bowl, toss the beef with 1/4 cup cornstarch until each piece is lightly coated.

Step 2: Fry the beef. Heat 1/4 cup vegetable oil in a large wok or skillet over medium-high heat. Working in batches if necessary to avoid overcrowding, add the beef in a single layer and fry for 2-3 minutes per side until browned and crispy. Remove the beef with a slotted spoon and set aside on a plate lined with paper towels to drain excess oil.

Step 4: Sauté aromatics. Drain all but 1 tablespoon of oil from the wok. Add the minced garlic, grated ginger, and the white parts of the green onions to the wok. Sauté for 1 minute until fragrant.

Step 5: Combine and thicken. Pour the prepared sauce into the wok and bring to a simmer, stirring constantly. Let it simmer for 2-3 minutes, or until the sauce begins to thicken. It should be glossy and slightly reduced.

Step 6: Finish the dish. Return the fried beef to the wok, tossing gently to coat it evenly with the sauce. Cook for another 1-2 minutes until the beef is heated through and well-glazed.
