Heat the butter in a wide pan over medium heat. Add the onion, black pepper, salt, thyme, celery, and pimento peppers. Lower the heat to medium-low and cook for 3 minutes.
Push everything to the side of the pan, clearing the center. Add the chicken bouillon powder and toast lightly.
Stir in the roucou and mix well to combine the flavors. Cook for another 2 minutes.
Add the washed and drained rice, stirring gently to coat with the seasonings.
Pour in the chicken stock and water. Increase the heat and bring to a boil.
Reduce to a simmer, partially cover with a lid, and cook for 25 minutes.
Turn off the stove, cover fully, and let the rice rest on the hot burner for 10–15 minutes.
Fluff with a fork and fold in the chopped chives before serving. I enjoy this with Stewed Oxtail as well as Jamaican Steamed Snapper. Optional Ingredients: 1 teaspoon grated garlic | 1 teaspoon grated ginger | 1 small scotch bonnet pepper (finely diced) or dried pepper flakes. To make this rice dish fully vegan or vegetarian, use vegan or vegetarian stock and stock powder.
