How to prepare your Black Pepper Beef:

1. Thaw out the Beef cubes in the fridge overnight.
2. In a clean deep pan, pour your choice of cooking oil to around 1 inch high, or just enough for deep frying. Heat the oil over medium heat until the temperature reaches 170 C, for around 15-18 minutes. Note: If without a thermometer, dip the end of a wooden spoon or chopstick into oil. If the oil steadily bubbles around the utensil, it should be ready. If bubbling is too vigorous, oil is too hot.
3. Deep fry the beef cubes until medium well, for around 3 minutes. If needed, fry in batches to avoid overcrowding the pan.
4. Shake off excess oil and transfer to a clean bowl.
5. Heat the sauce in a pan over medium heat (for around 3 minutes), or in the microwave just until warmed through (for around 45 seconds).
6. Pour the sauce over the fried beef cubes and toss until beef is well coated.
7. Transfer to a plate and serve hot.
