Foolproof Rice

(This is from memory, but I'm 95% sure the proportions are right.)

1 1/2 tsp butter or olive oil
1 cup rice
2 cups boiling water
1/2 tsp kosher salt

Preheat the oven to 400. Heat the butter or oil over moderate heat in an ovenproof pan. Add the rice and stir until the rice is coated and fragrant. Add the water and salt, and cover. Bake in the oven for 20 minutes. Serves 4.
