Marinate the Chicken: Begin by marinating your chicken pieces in the Adobo marinade. In a bowl, combine vinegar, soy sauce, minced garlic, bay leaves, and black peppercorns. Mix well. Add the chicken pieces to the marinade, ensuring they are coated evenly. Allow the chicken to marinate for at least 30 minutes, or you can marinate it overnight in the refrigerator for more intense flavor.

Preheat the Air Fryer: Preheat your air fryer to 375°F (190°C). This step is crucial to ensure even cooking and crispiness.

Prepare the Chicken: Remove the chicken from the marinade, allowing any excess liquid to drip off. You can reserve some of the marinade for later use.

Air Fry: Place the chicken pieces in the air fryer basket. To achieve a crispy exterior, mist the chicken with cooking oil or use an oil sprayer. Make sure the chicken is not overcrowded, allowing air to circulate around each piece. Cook the chicken in the air fryer for about 20-25 minutes, flipping them halfway through the cooking time.

Check for Doneness: As cooking times may vary depending on your air fryer model and the thickness of your chicken pieces, it's essential to check the internal temperature of the chicken. The chicken should reach an internal temperature of 165°F (74°C) for safe consumption.

Serve: Once the chicken is golden brown and has reached the desired internal temperature, remove it from the air fryer. You can serve it with the reduced Adobo sauce from the marinade as a dipping sauce or drizzle it over the chicken pieces for added flavor.
