Beef Stir-Fry with Savory Oyster Sauce

Cooking Instructions:

1. Prepare the Beef:

   • Slice the Beef: Cut the lean beef steak into strips about 5cm long and 5mm thick, ensuring you slice against the grain. This technique helps keep the meat tender.
   • Marinate: In a mixing bowl, combine the beef with 1 tablespoon of light soy sauce, 2 teaspoons of sesame oil, 1 tablespoon of Shaoxing rice wine (or dry sherry), and 2 teaspoons of cornflour. Mix well until the beef is fully coated.
   • Rest: Allow the beef to marinate for 20 minutes at room temperature. This step enhances the flavor and tenderness of the meat.

2. Stir-Fry the Beef:

   • Heat the Wok: Place a wok over high heat and let it heat up until it's very hot. This ensures a good sear on the beef.
   • Add Oil: Pour in 3 tablespoons of groundnut oil. Wait until the oil starts to shimmer and lightly smoke, indicating it’s hot enough.
   • Cook the Beef: Add the marinated beef slices to the wok in a single layer, ensuring not to overcrowd the pan. Stir-fry for about 5 minutes or until the beef is browned and cooked through. Use a spatula to continuously toss the beef for even cooking.
   • Drain: Once cooked, transfer the beef to a colander set over a bowl to drain excess oil. Discard the drained oil to prevent greasiness in the final dish.

3. Cook the Peppers:

   • Wipe the Wok: Clean the wok with a paper towel to remove any leftover residue and oil.
   • Stir-Fry the Peppers: Reheat the wok over high heat and add the diced red and green peppers. Stir-fry for 3-4 minutes until they become tender but still crisp, maintaining some texture for contrast.

4. Combine with Sauce:

   • Add Oyster Sauce: Pour in 3 tablespoons of oyster sauce and stir to combine with the peppers. Allow it to come to a gentle simmer.
   • Return Beef to Wok: Add the drained beef slices back into the wok. Toss everything together thoroughly to coat the beef and peppers in the oyster sauce, cooking for an additional 1-2 minutes to heat through.

5. Serve:

   • Plating: Transfer the stir-fried beef and peppers onto a serving platter.
   • Garnish: Top with 2 finely shredded spring onions for a fresh crunch and added flavor.
   • Enjoy: Serve immediately with steamed rice or noodles to soak up the delicious sauce, and enjoy a satisfying meal!
