Instructions

1. Prepare the beef: Thinly slice flank steak against the grain and place in a medium bowl.
2. Make the marinade: In a separate bowl, whisk together sesame oil, garlic, ginger, soy sauce, brown sugar, black pepper, and hot water until sugar dissolves. Pour marinade over beef, stir well, cover, and refrigerate for at least 4 hours or overnight for best flavor.
   Tip: Let marinated beef rest at room temperature for 30 minutes before cooking so it sears properly.
3. Cook the beef: Heat a large heavy skillet or non-stick pan over high heat (no extra oil needed). When the pan is hot, add the beef in a single layer. Cook without stirring for 2–3 minutes until browned, then stir and cook an additional 3–5 minutes until fully cooked, liquid has evaporated, and beef is caramelized.
4. Toast tortillas: Warm tortillas in a dry skillet or directly over a gas flame, turning often until lightly charred.
5. Make the sauce: In a small bowl, whisk together sour cream, mayonnaise, garlic powder, Sriracha, and lime juice. Transfer to a small bag or squeeze bottle for easy drizzling.
6. Assemble the tacos: Place beef onto warm tortillas, top with shredded cabbage, cilantro, avocado slices, and a drizzle of taco sauce. Finish with a squeeze of lime juice if desired.
