"Kaleh Joosh" is one of the traditional Iranian dishes made from key ingredients such as kashk (fermented yoghurt commonly used in Persian cuisine, also available at Middle Eastern shops or online) and onions, resulting in a unique and distinctive flavour from the combination of its primary components.

As a significant amount of Kashk is used in preparing "Kaleh Joosh," it becomes a rich source of calcium, offering exceptional properties. It's important to note that different regions may have variations of this dish. The authenticity of this dish is associated with the province of Isfahan, and other provinces like Yazd, Zanjan, Semnan, and Khorasan also prepare it in their distinctive styles.
