How long does the Biryani need to be in the cooker before it is ready to be served

Solutions:

If using basmati rice, cook it for about 3 to 5 minutes, do not let it whistle. If using normal rice that is slightly on the harder side to cook allow it to whistle once. If cooking in pot, cook until the rice is done. If rice is under cooked, you can also sprinkle little water and cook further.
