Zereshk Polo ba Morgh is a classic Persian rice dish featuring fragrant saffron rice topped with tender pieces of chicken and tangy barberries, which are dried berries similar to cranberries. The rice is typically flavored with saffron, giving it a vibrant golden color and a subtle floral aroma. The chicken is marinated in a mixture of yogurt, lemon juice, and spices before being cooked and layered over the rice. The tartness of the barberries provides a delightful contrast to the savory chicken and aromatic rice, creating a harmonious balance of flavors.
