Combine the 30g of roughly chopped scallions, 15g of fresh ginger, 12g of garlic cloves, 8g of fresh thyme leaves, 6g of ground allspice, 4g of ground cinnamon, 3g of ground nutmeg, 2g of cayenne pepper, 8g of brown sugar, 30ml of the lime juice, 45ml of soy sauce, and 30ml of vegetable oil in a food processor. Blend until completely smooth — stopping to scrape down the sides once or twice to ensure the ginger and scallion are fully processed rather than leaving fibrous pieces. The marinade should be a uniform, deep green-brown paste with a pungent, complex aroma combining the warm spices, fresh herbs, and garlic-ginger sharpness simultaneously. The food processor is the correct tool for this preparation rather than a blender — the paste consistency rather than a liquid consistency is what adheres to the chicken's surface and penetrates the scored cuts during marinating. Reserve 60ml of the blended marinade in a small separate bowl for basting during cooking — this reserved portion must be set aside before the raw chicken contacts the marinade to prevent cross-contamination with a portion that will be applied during the cooking's final stages.

Pat each chicken thigh completely dry on both sides with paper towels — removing surface moisture ensures the marinade paste adheres directly to the meat rather than being diluted by surface water. Using a sharp knife, score the smooth top side of each thigh with shallow diagonal cuts approximately 2cm apart — just deep enough to open channels through the surface without cutting all the way through the flesh. The scoring serves a specific purpose beyond aesthetics: the channels allow the marinade paste to penetrate the meat's interior during the marinating period rather than sitting exclusively on the surface, which produces the deepest jerk flavour through the cooked chicken rather than only on its exterior. Place the chicken thighs in a large bowl and pour the remaining marinade over them. Using your hands, massage the paste thoroughly into every surface — working it into the scored cuts and turning the thighs to coat the undersides completely. Cover tightly and refrigerate for a minimum of 2 hours. Overnight marinating — 12–24 hours — produces a measurably more deeply flavoured result as the allspice, cinnamon, and thyme penetrate further into the muscle fibres and the soy sauce's salt draws moisture from the meat and redistributes it as flavoured brine throughout.

Remove the marinated chicken thighs from the refrigerator 20 minutes before cooking — allowing them to approach room temperature reduces the temperature gradient between the cold interior and the exterior, producing more even cooking throughout. Heat a large cast iron skillet or grill pan over medium-high heat until properly hot — 2–3 minutes of preheating. Remove each thigh from the marinade and allow the excess to drip off briefly — thick excess marinade on the surface will burn rather than caramelise. Place the thighs smooth-side down in the skillet. Leave completely undisturbed for 8–10 minutes. The jerk marinade's sugar and soy undergo Maillard caramelisation and partial charring against the hot cast iron surface — the deep char marks and blackened edges that develop during this undisturbed period are not burning but the specific caramelised-char that defines authentic jerk cooking. The char produces bitter, smoky, intensely aromatic compounds from the allspice, thyme, and sugar that are essential to jerk flavour's specific complexity. After 8–10 minutes, flip each thigh and brush the top surface immediately with the reserved marinade that was set aside before the raw chicken was added. Cook the second side for a further 8–10 minutes until the internal temperature reads 75°C throughout the thickest part of the thigh. Transfer to a plate and rest for 5 minutes — the resting period allows the internal juices to redistribute through the meat before slicing. Slice into strips for bowl assembly.

While the chicken rests, increase the heat under the same skillet to high — do not clean the pan, as the jerk marinade char in the pan contributes flavour to the pineapple's charring. Add the 200g of pineapple chunks directly to the hot pan without any additional oil. The pineapple's natural sugars are extremely concentrated — they caramelise and develop char marks within 2–3 minutes per side at high heat. Cook undisturbed for 2–3 minutes until deep golden-brown char marks develop on the contact surface, then turn each piece and char the second side for 2–3 minutes. Charred pineapple undergoes a specific transformation: the surface sugars caramelise to a deep, slightly smoky sweetness while the interior retains its bright, acidic tropical freshness — the combination of exterior caramelisation and interior juiciness provides a specific flavour contrast that raw pineapple cannot produce. Remove and set aside.

In a small bowl, whisk together the 120g of sour cream, 30ml of lime juice, 20g of chopped fresh cilantro, and 2g of minced garlic until completely smooth. Season with salt to taste — the crema should taste prominently of lime and cilantro with a background garlic note and sufficient salt to season the components it drizzles over. It should be thick enough to drizzle in a controlled stream rather than pouring freely. In a small saucepan, warm the drained and rinsed black beans with the 2g of ground cumin and a small splash of water over medium heat for 3–4 minutes until heated through. The cumin blooms in the warm water around the beans, distributing its earthy, slightly citrusy warmth through the beans evenly.

Divide the coconut rice among four wide bowls. Top each bowl with sliced jerk chicken strips arranged across the rice surface. Distribute the components in distinct sections alongside the chicken: 100g of black beans per bowl, charred pineapple chunks, 25g of red bell pepper slices, and 20g of thinly sliced red onion. The red bell pepper and red onion are served raw — their fresh, crunchy, slightly sharp characters provide the textural and flavour contrast against the warm, cooked, smoky chicken. Drizzle the lime-cilantro crema generously over each bowl, extending it across both the chicken and the rice rather than concentrating it at the centre. Scatter fresh cilantro leaves over each bowl. Place lime wedges alongside for squeezing at the table — the fresh lime juice at serving amplifies the bowl's citrus brightness and provides volatile aromatic compounds that the marinated lime cannot replicate after cooking.
