Sohan (Farsi, "rasp") is a traditional Persian saffron brittle toffee made in Iran. It is made with sprouted wheat flour and flour, butter or vegetable oil, sugar and corn syrup, and may be enriched with egg yolks. It is usually generously scented with rose water, saffron, cardamom, and slivers of almond and pistachio.
It is historically associated with the city of Qom, to a degree that it is also known as "Sohan-e Qom" (Sohan of Qom").
