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:
- 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.
- 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.
- Seal the beef and marinade in a bag or container. Refrigerate for 2 hours until the flavors have fully penetrated the muscle fibers.
- Place a cast iron skillet over high heat. Wait until the pan begins to slightly smoke, then add 1 tbsp of neutral oil.
- Add the beef in small batches in a single layer. Note: Do not crowd the pan or the meat will steam instead of sear.
- Let the meat sear undisturbed for 1-2 minutes until a deep mahogany crust forms.
- Quickly toss the meat for another 1-2 minutes until just cooked through, then remove from the pan immediately.
- Garnish with sliced green onions and toasted sesame seeds before serving.
