Ingredients:

  • 1 lb beef sirloin, thinly sliced against the grain
  • 1/4 cup soy sauce
  • 2 tbsp brown sugar
  • 4 cloves garlic, finely minced
  • 2 tbsp calamansi juice
  • 1 tsp black pepper
  • 1 tbsp cooking oil

Instructions:

  1. In a medium bowl or a Ziploc bag, combine the soy sauce, brown sugar, minced garlic, calamansi juice, and black pepper. Whisk until the sugar is fully dissolved.
  2. Add the thinly sliced beef to the marinade, ensuring every piece is coated. Seal and refrigerate for at least 4 hours (up to 24 hours for best flavor).
  3. Heat the cooking oil in a skillet over medium-high heat until it begins to shimmer.
  4. Working in batches to avoid crowding the pan, lay the beef strips flat and cook for 2-3 minutes per side.
  5. Toss the beef strips in the remaining marinade reduction during the last 30 seconds of cooking until they are mahogany-colored and slightly caramelized.
