Prepare the Chicken: In a large mixing bowl, beat the egg lightly. Add the chicken pieces and stir to coat them thoroughly. Then, dredge the chicken in the cornstarch, ensuring each piece is well covered.

Fry the Chicken: Heat the oil in a large skillet over medium-high heat. Once the oil is hot, add the chicken in a single layer and fry for 3 to 4 minutes on each side, or until golden brown and cooked through.

Make the Honey Garlic Sauce: In the same skillet, reduce the heat to medium and add the minced garlic. Sauté for about 1 minute until fragrant. Then, pour in the honey, chicken broth, rice vinegar, and soy sauce. If you prefer a spicy kick, add the red pepper flakes at this stage.

Thicken the Sauce: In a small bowl, combine 1 tablespoon of cornstarch with 2 tablespoons of water, stirring until smooth. Add this mixture to the sauce in the skillet, cooking over medium heat while stirring constantly until the sauce thickens, about 2 to 3 minutes.

Combine Chicken with Sauce: Return the cooked chicken to the skillet and toss it in the honey garlic sauce, ensuring all pieces are well coated. For a richer flavor, you can add a tablespoon of butter at this point and stir until it melts.

Serve: Serve the Honey Garlic Chicken hot over white rice or alongside steamed vegetables for a complete meal. Enjoy this delightful sweet and savory dish!
