  • 1 tablespoon Oil for beef marinade
  • 0.25 teaspoon Salt (for marinade)

Instructions

  1. Cook Thai fragrant rice

    Rinse the rice under cold water until the water runs clear. Combine 400 g rice with the appropriate amount of water (about 1 cup rice to 1.25 cups water) in a rice cooker or pot. Bring to a boil, then reduce heat, cover, and simmer for 12‑15 minutes. Remove from heat and let steam, covered, for 10 minutes.

    Time: PT20M

    Temperature: Boiling

  2. Marinate the beef

    Slice the beef lengthwise into thin strips, then cut into bite‑size cubes. Place the beef in a mixing bowl and add ¼ tsp salt, 1 Tbsp thick soy sauce, 1 Tbsp oyster sauce, 1 Tbsp oil, and 1 tsp tapioca flour. Mix thoroughly, cover, and refrigerate while you prepare the vegetables.

    Time: PT12M

  3. Prepare the vegetables

    Peel the cucumber and slice into rounds. Quarter the lemon. Slice the tomato and onion into rounds. Peel the garlic cloves and mince them finely.

    Time: PT10M

  4. Stir‑fry the rice

    Heat the wok over high heat. Add 3 Tbsp oil and swirl. When the oil shimmers, add half of the minced garlic and sauté until golden (about 30 seconds). Add the cooked rice, 70 g tomato concentrate, and 1 Tbsp oyster sauce. Stir‑fry, tossing constantly, until the rice is evenly coated and heated through, about 5 minutes. Transfer to a warm bowl and keep covered.

    Time: PT7M

    Temperature: High

  5. Stir‑fry the beef

    Wipe the wok clean, return to high heat, and add the remaining 3 Tbsp oil. Add the remaining minced garlic and sauté until fragrant (≈30 seconds). Add the marinated beef and stir‑fry quickly, about 1‑2 minutes, until just browned but still pink inside. Remove from heat.

    Time: PT4M

    Temperature: High

  6. Assemble the bowls

    On each plate, lay a lettuce leaf, then arrange cucumber, tomato, and onion rounds. Spoon a generous portion of the stir‑fried rice onto the center, top with beef cubes, and place a lemon wedge on the side. Allow each diner to season with salt, pepper, and fresh lemon juice.

    Time: PT5M
