In a blender, combine tomatoes, scotch bonnet pepper and onions; purée. Pour out half the purée into a bowl; set aside. Add the bell peppers to the purée remaining in the blender and pulse until smooth. Add to the mixture that was set aside and stir to combine.

Heat vegetable oil in a large pot over medium heat. Add blended vegetables along with the salt, curry powder, ground chile pepper, garlic powder, onion powder, bay leaves, ginger and thyme. Bring mixture to a boil.

Stir in the rice until well mixed, then reduce the heat to low.

Cover pot and let cook until rice is al dente, about 45 minutes. Check after 30 minutes; if rice is sauce-logged, remove the lid to cook off the excess sauce. If rice seems dry, stir in 1 to 2 cups water. Allow the rice at the bottom of the pot to char a bit to infuse it with a smoky flavor.
