In a medium size pot, heat the oil. Add onions, garlic, and rice, and saute for 5 min. stirring frequently. Add the water, herbs, salt, pepper and butter. Stir til it is all mixed together. Bring to a boil, then reduce heat and simmer, covered for about 40 minutes, or until the water is absorbed. Check after 30 min. if there is a lot of water left, remove the cover and finish the cooking. Let the cooked rice stand in the pot, covered for 15 minutes. ~-
