# Steps:

01 - In a medium bowl, toss the sliced beef with 1 tablespoon soy sauce and 1 tablespoon cornstarch. Let it marinate for 10 minutes.
02 - Combine 4 tablespoons cornstarch, 2 tablespoons all-purpose flour, salt, and black pepper in a shallow dish. Dredge the marinated beef strips thoroughly in the mixture.
03 - Heat vegetable oil in a deep skillet or wok to 350°F. Fry beef strips in batches for 2 to 3 minutes until golden and crispy. Drain on paper towels.
04 - Combine soy sauce, rice vinegar, brown sugar, hoisin sauce, ketchup, minced garlic, grated ginger, chili flakes, and water in a small saucepan. Simmer over medium heat, stirring until sugar dissolves and sauce thickens slightly, about 2 to 3 minutes.

06 - Immediately garnish with sliced green onions and toasted sesame seeds. Serve at once.

# Expert Advice:

01 -
  • That impossible texture—shatteringly crispy on the outside, impossibly tender within.
  • The sauce is tangy and sweet without being cloying, coating every strip with serious flavor.
  • Ready in 40 minutes from fridge to table, no special equipment needed.
02 -
  • Double-frying creates an almost supernatural crispness—fry once, let cool slightly on paper towels, then fry again for 1 minute if you want to impress people.
  • Never sauce the beef more than a minute or two before serving, or the coating will surrender to the moisture and lose its signature crunch.
03 -
  • Pat the beef dry before dredging; any moisture on the surface creates steam that softens the coating before it hits the oil.
  • Keep your sauce ingredients measured and ready before you start frying—there's no time to gather things once the oil is hot and the beef is cooking.
