Creating the perfect Grilled Achiote Chicken is easy! Follow these steps for a delicious outcome:

1. Prepare the Marinade: In a bowl, combine achiote paste, orange juice, lime juice, olive oil, garlic, cumin, oregano, salt, and black pepper. Mix the ingredients until well blended.
2. Marinate Chicken: Place the chicken thighs in a resealable plastic bag or a bowl. Pour the marinade over the chicken, ensuring all pieces are covered. Seal the bag or cover the bowl and refrigerate for at least 1 hour (or overnight for better flavor).
3. Preheat Grill: Heat your grill to medium-high heat, approximately 375°F (190°C).
4. Grill Chicken: Remove the chicken from the marinade and allow excess to drip off. Place the chicken on the grill. Cook for about 6-7 minutes on one side. Flip and cook for another 6-7 minutes until fully cooked and internal temperature reaches 165°F (74°C).
5. Check for Doneness: Ensure that the chicken is cooked through. The juices should run clear when pierced at the thickest part.
6. Rest Chicken: Remove the chicken from the grill and let it rest for 5 minutes before slicing.
7. Prepare for Serving: Slice the chicken into strips or serve whole as per your preference.

These simple steps will guide you to create the most flavorful Grilled Achiote Chicken effortlessly!
