Step 1: In a large bowl, season the chicken thighs with curry powder, turmeric, allspice, thyme, salt, and black pepper. Massage the spices into the chicken and let it marinate for 15 minutes.

Step 2: Heat the vegetable oil in a large skillet or pot over medium heat. Add the chicken thighs, skin-side down, and sear for 4-5 minutes until golden brown. Flip and cook for another 3 minutes. Remove the chicken and set aside.

Step 3: In the same skillet, add the chopped onion, garlic, and ginger. Sauté for 2-3 minutes until fragrant.

Step 4: Add the red bell pepper and scotch bonnet pepper (if using) to the skillet. Cook for another 2 minutes.

Step 5: Pour in the coconut milk and chicken broth, stirring to combine. Bring the mixture to a gentle simmer.

Step 6: Return the chicken thighs to the skillet, ensuring they are submerged in the sauce. Cover and simmer for 25-30 minutes until the chicken is cooked through and tender.

Step 7: Taste and adjust seasoning with salt and pepper if needed. Serve hot with steamed rice or Jamaican dumplings.
