1. Marinate the Chicken

1. Slice the chicken breast into thin strips.
2. In a mixing bowl, combine the chicken with the marinade ingredients: dark soy sauce, garlic and ginger paste, sesame oil, sugar, and white pepper.
3. Let the chicken marinate for at least 10 minutes to absorb the flavors.

2. Prepare the Sauce

1. In a small bowl, mix the stir-fry sauce ingredients: dark soy sauce, honey, sriracha, and lemon juice.
2. Set aside for later use.

3. Coat and Fry the Chicken

1. Add an egg white to the marinated chicken and mix well.
2. Gradually coat the chicken pieces with cornflour, ensuring each piece is fully covered.
3. Heat vegetable oil in a wok or frying pan to 180°C (356°F).
4. Fry the chicken in small batches for 1-2 minutes until light golden. Remove and drain on paper towels.
5. Double-fry the chicken for an additional 2-3 minutes to achieve extra crispiness.

4. Make the Sauce

1. In a clean pan, heat a tablespoon of vegetable oil over medium heat.
2. Sauté the garlic and ginger paste for 5-10 seconds until fragrant.
3. Pour in the prepared stir-fry sauce and stir for 30 seconds until slightly thickened.
