Vermicelli toasted in oil until golden before the rice goes in, then both cooked together in broth. That first browning is the whole flavour of the dish. Five ingredients, half an hour, four servings.
Toasting the vermicelli first is the entire point. Two or three minutes in oil until the strands go golden gives the dish the toasted, nutty flavour it is known for, and skipping it leaves you with rice that happens to have pasta in it. Watch it closely: vermicelli goes from pale to golden to burnt in under a minute at the end. Three cups of broth is the right amount for a cup of rice plus three quarters of a cup of vermicelli. The recipe used to call for two, which is not enough for that much dry starch and leaves the grain hard. Judge it by the rice all the same, and if it is still firm when the pot is dry, add a splash of hot broth and give it five more covered minutes. Do not lift the lid before then: the steam trapped under it is doing the cooking.
