Walnut + Kashk Soup

In Persian, kaleh jush literally means “at boiling point.” That may be because once the kashk is added, the soup should be removed from the heat as soon as it boils. As well as variations of it in different regions of Khorasan, it is made in many parts of Iran such as, Isfahan, Yazd, and Azarbaijan, known by different names (kal jush, kala jush, qoruti, kashk jush, and dugh garmeh). When I cooked it in Kerman, we used pistachios instead of walnuts.
