Step 2

In a bowl, combine the chicken with a pinch of salt, a pinch of white pepper, the egg and 2 tbsp cornstarch to marinate.

Step 3

Whisk the flour, baking powder, salt, onion salt and garlic powder together in a bowl, then stir in ¾ cup water to make a smooth batter about as thick as pancake batter. Tip in the marinated chicken and turn the pieces until each one is coated.

Step 4

Deep fry the chicken at 350°F for 3–4 minutes until golden brown, loosening pieces so they don't stick together. Transfer to a plate and set aside.

Step 5

Add the sauce to a hot wok along with the broccoli. Bring to a boil.

Step 6

Whisk the remaining 2 tbsp cornstarch with 4 tbsp water. Gradually add to the stir-fry, stirring, until the sauce reaches the desired thickness.

Step 7

Add the fried chicken to the wok and stir-fry for 1 minute. Serve over rice, garnished with scallions.
