Barberry rice, also known as Zereshk Polo, is a traditional Persian dish that combines flavorful ingredients such as chicken, rice, and barberries. The dish is cooked by first marinating chicken pieces in a mixture of yogurt and spices, then layering them with cooked rice and barberries in a pot to create a delicious and aromatic meal. The tangy and sweet flavor of the barberries pairs perfectly with the tender chicken and fluffy rice, making it a popular dish in Iranian cuisine. Serve with a side of salad or yogurt for a complete and satisfying meal.
