In a large skillet, heat the oil over medium-high heat until shimmering. Add the onion, bell peppers, salt and thyme. Cook until soft, about 5 minutes.
Add in the tomato paste and cook until it turns a deep brick red, then add the curry powder and scotch bonnet pepper.
Add the coconut milk, shrimp stock and potatoes. Simmer for 10 minutes or until the potato chunks are cooked through.
Fold in the seasoned shrimp and chopped tomatoes and simmer for another 5 minutes or until the shrimp turn pink. Be careful not to overcook the shrimp as they will become tough.
Serve over hot white rice and garnish with chopped cilantro.
