Instructions

  1. Step 1: Preheat oven to 400°F. In a small bowl, whisk together 1/4 cup dark rum, 2 tbsp brown sugar, 1 tsp garlic powder, 1/2 tsp ground allspice, 1 tsp salt, and 1/2 tsp black pepper to create the rum glaze.
  2. Step 2: Rub 1.5 lbs pork tenderloin with 2 tbsp olive oil, then brush generously with half of the rum glaze. Place on a rimmed baking sheet and roast for 20 minutes.
  3. Step 3: Brush the pork again with remaining rum glaze and roast for an additional 10-15 minutes, or until internal temperature reaches 145°F. Remove from oven and rest for 10 minutes before slicing.
  4. Step 4: While pork roasts, place 2 lbs peeled and cubed sweet potatoes in a large pot and cover with water. Bring to a boil and cook for 15 minutes until tender.
  5. Step 5: Drain sweet potatoes and mash with 1/2 cup coconut milk, 1/4 tsp ground cinnamon, and 1 tbsp chopped fresh thyme until creamy and smooth. Season with salt to taste.
  6. Step 6: Serve sliced pork tenderloin over a bed of the Caribbean sweet potato mash for a rich and flavorful dinner.
