Additionally, letting the dish relaxation after cooking offers the rice a bit of additional time to take in the liquid. If the rice remains to be agency on the finish of the cooking time, add a couple of half cup of water or broth, gently stir, cowl, and prepare dinner for one more 30-45 minutes till the rice is tender.
