Ingredients:

  • 1/2 cup (120ml) soy sauce
  • 1/4 cup (60ml) brown sugar, packed
  • 2 tbsp (30ml) toasted sesame oil
  • 2 tbsp (30g) grated Asian pear
  • 1 tbsp (15g) fresh ginger, minced
  • 3 cloves (15g) garlic, minced
  • 1 tbsp (15ml) rice vinegar
  • 1/2 tsp (2.5g) black pepper
  • 1.5 lb (680g) beef sirloin, sliced paper-thin against the grain
  • 2 green onions (30g), thinly sliced
  • 1 tbsp (15ml) neutral oil

Instructions:

  1. Combine soy sauce, brown sugar, sesame oil, grated pear, ginger, garlic, vinegar, and pepper in a mixing bowl. Whisk until the sugar is completely dissolved.
  2. Add the thinly sliced beef to the marinade. Note: Use your hands to massage the sauce into the meat for 60 seconds to ensure every fiber is coated.
  3. Seal the beef and marinade in a bag or container. Refrigerate for 2 hours until the flavors have fully penetrated the muscle fibers.
  4. Place a cast iron skillet over high heat. Wait until the pan begins to slightly smoke, then add 1 tbsp of neutral oil.
  5. Add the beef in small batches in a single layer. Note: Do not crowd the pan or the meat will steam instead of sear.
  6. Let the meat sear undisturbed for 1-2 minutes until a deep mahogany crust forms.
  7. Quickly toss the meat for another 1-2 minutes until just cooked through, then remove from the pan immediately.
  8. Garnish with sliced green onions and toasted sesame seeds before serving.
