Ingredients
Beef Coating
- 360 g (¾ lbs) thin-cut sirloin steaks (approx 3 thin steaks) cut into thin strips
- 1 small egg
- 4 tbsp cornflour (cornstarch)
- ¼ tsp salt
- ¼ tsp black pepper
- ⅛ tsp white pepper
For Frying
- 4 ½ tbsp sunflower oil, divided
Sauce and Vegetables
- 1 medium onion, peeled and sliced into thin strips
- 1 red chilli, finely sliced (discard seeds if preferred less heat)
- 1 tsp minced ginger
- 3 garlic cloves, peeled and minced
- 2 tbsp rice vinegar
- 3 tbsp dark soy sauce
- 2 tbsp tomato puree (use tomato paste in the US)
- 6 tbsp caster sugar or superfine sugar
- 2 tbsp tomato ketchup
- 2 tbsp sweet chilli sauce (preferably Thai-style)
Instructions
- Coat the Beef: Place the thin-cut sirloin steak strips in a bowl and add the egg. Mix thoroughly to coat all the steak strips evenly in egg.
- Add Dry Ingredients: Sprinkle cornflour, salt, black pepper, and white pepper over the coated steak. Toss everything together until the steak strips are thoroughly coated with a sticky mixture.
- Heat the Oil: Heat 3 tablespoons of sunflower oil in a large frying pan or wok over high heat until the oil is very hot.
- Fry the Beef in Batches: To achieve maximum crispiness, add half the beef strips into the hot oil, spreading them out for even frying. Fry for approximately 5-6 minutes, allowing the strips to turn dark brown and crispy, stirring gently 3-4 times to avoid breaking the crisp coating.
- Drain the Beef: Remove the crispy beef with a slotted spoon or tongs and place on a bowl lined with kitchen paper to absorb excess oil. Repeat frying the second batch with 1 tablespoon of oil.
- Sauté Vegetables: Add the remaining ½ tablespoon of oil to the pan, reduce heat to medium, and add the sliced onion. Cook for 2 minutes until softened.
- Add Aromatics: Stir in the finely sliced red chilli, minced ginger, and minced garlic. Cook while stirring continuously for 30 seconds to release their flavors.
- Create the Sauce: Pour in rice vinegar, dark soy sauce, tomato puree, caster sugar, tomato ketchup, and sweet chilli sauce. Increase heat to high and let the sauce bubble gently for a couple of minutes until it begins to reduce and thicken slightly.
- Combine and Heat Through: Return the crispy beef to the pan with the sauce. Stir well to coat all beef strips and cook for 1-2 minutes until the beef is heated through and flavors are combined.
- Serve: Serve immediately with cooked rice or noodles for a complete meal.
Notes
- You can adjust the level of heat by removing chilli seeds before slicing.
- For a gluten-free version, use gluten-free soy sauce.
- Work quickly when frying the beef to maintain the oil temperature for best crispiness.
- Tomato puree can be substituted with tomato paste in the US, but adjust sugar to balance acidity if needed.
- Adding a pinch of white pepper gives an authentic subtle heat different from black pepper.
