Soan papdi (also known as san papri, shompapri,sohan papdi, shonpapdi or patisa) is a popular dessert in the Indian subcontinent. The term sohan is of Persian origin. It bears some resemblance to the Persian sohan pashmaki, which gave rise to the Turkish pişmaniye. It is usually cube-shaped or served as flakes, and has a crisp and flaky texture. Traditionally sold loose in rolled paper cones, modern industrial production has led it to being sold in the form of tightly-formed cubes.
Its main ingredients are sugar, gram flour, flour, ghee, almond, milk, and cardamom.
There are different types of Sohan including honey Sohan, sesame Sohan, Sohan halwa, almond Sohan, Sohan Gazi, Sohan Loghmeh, butter Sohan, Sohan Pashmaki (cotton candy) and Dessert Sohan. [...] Some people believe that when Mozaffar ad-Din Shah Qajar travelled to Qom and he was entertained with Halwa Qomi, he analogized it to a rasp (Sohan is the Persian word meaning rasp or file) which digested the food he had eaten very well.
Believed to have been derived from the Turkish Pismaniye, soan papdi is often referred to as Indian candy floss as it has a strand-like texture that makes it so soft and flaky.
