01 - In a mixing bowl, combine the chicken thighs, jerk seasoning, 1 tablespoon of vegetable oil, and lime juice. Toss thoroughly to coat all pieces evenly. Cover and refrigerate for at least 15 minutes, or up to overnight for more intense flavor penetration.
02 - Heat the remaining 1 tablespoon of vegetable oil in a large skillet or Dutch oven over medium-high heat. Add the marinated chicken thighs and sear until deeply golden on both sides, approximately 3 to 4 minutes per side. Transfer the chicken to a plate and set aside; it will finish cooking in the rice.
03 - In the same skillet, sauté the chopped onion, minced garlic, and diced red bell pepper for about 3 minutes until softened and fragrant. If using the scotch bonnet or habanero pepper, add it now and cook for an additional minute, stirring constantly.
04 - Stir in the long-grain rice, dried thyme, and ground allspice. Cook for 1 minute, stirring continuously to coat each grain with the seasoned oils and lightly toast the rice.
05 - Pour in the coconut milk and chicken broth. Season with salt and freshly ground black pepper to taste. Stir well to combine and bring the mixture to a gentle simmer.
06 - Nestle the seared chicken thighs into the rice mixture, pressing them down slightly. Cover with a tight-fitting lid, reduce the heat to low, and cook for 18 to 20 minutes until the rice is tender and has absorbed all the liquid.
07 - Remove the lid and scatter the frozen peas over the surface. Cook uncovered for 3 to 4 minutes, allowing the peas to warm through and any excess moisture to evaporate, yielding fluffy, separate grains.
08 - Fluff the rice with a fork and garnish with the sliced spring onions and chopped fresh cilantro. Serve immediately while hot.
