Wonderful recipe from Mark Bittman, who writes: "While this is the most basic version of Hainanese chicken, the best one is the provenance of devotees, who save the stock they don’t need for the rice, freeze it, and use it as a starting point for the next time they cook chicken this way. If you do this repeatedly, the stock will become stronger and stronger, as will the flavors of both chicken and rice. If you do this hundreds of times, the way restaurants do, the flavors will be quite intense. But even if you do it once, the dish is a total winner." The cooking/resting process requires some time, but it's well worth the effort!
