Ash-e Somagh - Persian Herb and Sumac Soup

It may officially be spring but the weather is still cold and windy. That means there's still plenty of time to make a warm pot of soup. This is also a good opportunity for me to use the recipe that inspired me in the only Iranian cookbook that I own! This cookbook was given to me by mother when I left home many years ago and  is called "Noosh-e Jan Konid" (Bon Appetit), by Mansoureh Amir
