Baghali polow, a rice dish packed with fresh green dill and fava beans is a dish that often makes an appearance during Nowruz. Fresh, green herbs are a mark of spring the world over and this is no exception among any Nowruz celebration. Tahdig, a saffron spiked brown crust, that is created to the bottom of the rice, makes this dish extra special. This month, we've included a pinch of the most expensive spice in the world- saffron threads- in this month's spice box. A little bit goes a long way here- a few threads of this exquisitely flavored, delicate rice, is just enough to flavor this special rice dish.
