Add the cinnamon, cardamom, turmeric, and cumin. Stir until chicken is coated. Add the dates, currants, and the PERDUE® Signature Chicken Stock. Raise the heat to high and bring to a boil and let boil for about 1 minute. Take the saucepan off the heat and immediately add the couscous and stir. Cover, and let stand for about 20 minutes or until all the liquid has been absorbed.
