Next, pour on the O.J. If you warmed the rice long enough, it will sizzle and sputter as the liquid hits the hot grains. Bring the mixture to a boil. Reduce to a simmer, cover, and cook until all the liquid is absorbed. This will take longer than regular rice because we made it with O.J. instead of water. Mine took 25+ minutes, but cooking times may vary. NOTE: If you use 50% OJ and 50% water, cooking time will be more like 16-20 minutes.
