Blend the spices, hot peppers, onions, garlic, soy sauce, water, and rum in a food processor or blender until smooth. (Alternatively, use a mortar and pestle, first chopping the ginger, onions, and garlic finely.) Pour the thick sauce over the chicken and marinate in resealable bags in the refrigerator overnight, or longer for added flavor. Brush marinated chicken with oil and grill or bake uncovered at 350 degrees F until cooked through (about 1 hour). Garnish with fresh lime slices. Serve with Red Stripe beer and feel the taste buds flare!
