Creating Authentic Jamaican Curry Chicken is easy when you follow these simple steps:

1. Marinate Chicken: In a large bowl, combine the chicken pieces with curry powder, allspice, salt, black pepper, and cayenne pepper. Let it marinate for at least 30 minutes, or overnight for more flavor.

2. Heat Oil: In a large pot or Dutch oven, heat vegetable oil over medium-high heat.

3. Sauté Aromatics: Add chopped onion, garlic, and ginger to the pot. Sauté for 3-5 minutes until the onions are soft and translucent.

4. Brown Chicken: Add the marinated chicken to the pot, browning it on all sides for about 5-7 minutes.

5. Add Vegetables: Stir in the chopped bell pepper, carrots, and green onions. Cook for another 2-3 minutes.

6. Pour in Coconut Milk: Add the coconut milk and enough chicken broth to cover the chicken. Stir well to combine.

7. Add Thyme: Toss in the fresh thyme sprigs for added flavor.

8. Simmer: Bring the mixture to a gentle boil, then reduce the heat to low. Cover the pot and simmer for 25-30 minutes, allowing the chicken to become tender and the flavors to meld.

9. Adjust Seasoning: Taste the sauce and adjust seasonings if necessary. You can add more salt or pepper according to your preference.

10. Serve: Once the chicken is cooked through and tender, remove from heat. Discard thyme sprigs and garnish with fresh lime or lemon juice before serving.
