This is a recipe that I have been making since I was a teenager. My Step-Father was Armenian, and we ate this pilaf often, with our evening meal. It has a great buttery flavor, and can be made with either brown rice or long grain, white rice. It's YUMMY either way. I learned to make it with just butter. However, using a combination of oil and butter, helps to keep smoking and burning to a minimum, while still imparting the great buttery taste. I have also made it with just olive oil, and also with a combination of butter and olive oil. Of course, the flavor is slightly different. I think it has the best flavor, when made with just 3 Tbsp of butter (no oil), but it is healthier with the butter/oil combination, and healthiest with 2 Tbsp oil and no butter.
