Follow these steps to create your delicious Authentic Jamaican Curry Chicken:

1. Marinate the Chicken: In a large bowl, combine chicken pieces with curry powder, allspice, salt, and black pepper. Mix thoroughly to coat the chicken well. Allow to marinate for at least 30 minutes.
2. Heat Oil: In a large pot or Dutch oven, heat vegetable oil over medium heat.
3. Sauté Aromatics: Add sliced onions, minced garlic, and grated ginger into the pot. Sauté until the onions turn translucent and fragrant, about 3-4 minutes.
4. Add Chicken: Add the marinated chicken to the pot and increase the heat to medium-high. Brown the chicken on all sides, about 5-7 minutes.
5. Add Coconut Milk: Pour in the coconut milk, stirring well to incorporate it with the chicken and spices.
6. Include Vegetables: Toss in the sliced bell pepper, carrot, and whole scotch bonnet peppers. Add more salt if desired.
7. Simmer: Lower the heat to medium-low. Cover the pot and let simmer for 25-30 minutes, stirring occasionally, until the chicken is cooked through and the sauce thickens.
8. Adjust Flavor: Taste the sauce and adjust the seasoning if needed. You can also remove the scotch bonnet at this point if you want to reduce the heat.
9. Garnish: Stir in chopped green onions and fresh cilantro before serving to enhance freshness.

These steps will guide you toward creating a truly wonderful dish that encapsulates the spirit of Jamaica.
