Soak the rice in water for 10–15 minutes. Drain, then add all the spices and mix well.
Preheat oven to 400°F.
Place rice in a baking pan (a Pyrex works well). Spread it out. Add 3 cups of boiling water — make sure water is covering the rice. Cover with two layers of aluminum foil. Poke the foil with a toothpick throughout the entire surface.
Gently place the chicken halves on top of the aluminum that has been poked with holes. Cover with another layer of aluminum foil very well.
Place in preheated oven for about 1½ hours. Check at 1 hour to see if chicken is cooked. Cooking time depends on size of chicken.
In the meantime, make the salsa.
