I guess when I was typing the recipe into the post, I omitted an entire sentence :-( The directions should have read:

1. In a 2-quart casserole, saute vermicelli in butter and oil until golden, stirring constantly. Stir in the rice and fry until glazed, about 1 minute. Add the boiling liquid (either water or chicken broth), and the salt and allow to boil 1 minute. Reduce the heat to low and simmer, covered, until liquid has been absorbed, about 18 minutes. Place a folded paper towel or terry towel over the rice, cover the pot, and let rest, with the heat turned off, 10 minutes before serving.
2. Sprinkle with one of the spices and fluff the rice with a fork.
