Making Panda Express Orange Chicken can be a fun and rewarding experience. Follow these steps for perfect results:

1. Prepare the Chicken: In a large bowl, mix together the flour, cornstarch, baking powder, salt, and black pepper. Gradually add water until a thick batter forms.

2. Coat the Chicken: Dip each piece of chicken into the batter, ensuring an even coating.

3. Heat the Oil: In a deep skillet or pot, heat about two inches of oil over medium-high heat.

4. Fry the Chicken: In batches, fry the chicken pieces for about 4-5 minutes or until golden brown and cooked through. Remove with a slotted spoon and place them on a paper towel-lined plate to drain excess oil.

5. Prepare the Sauce: In a medium saucepan, combine the orange zest, orange juice, sugar, soy sauce, rice vinegar, minced garlic, and grated ginger. Heat over medium heat until the sugar dissolves.

6. Thicken the Sauce: In a small bowl, mix cornstarch with water. Add this mixture to the sauce and stir until it thickens, approximately 2-3 minutes.

7. Combine: Pour the orange sauce over the fried chicken, tossing to coat evenly.

8. Serve Hot: Once coated, serve the Panda Express Orange Chicken immediately, garnished with sliced green onions and sesame seeds, if desired.

These clear steps will ensure you achieve that incredible flavor and satisfy your craving for Panda Express Orange Chicken!
