Sohan Mohammad Sima is a kind of the traditional confectionary which is provided by baking the compound of flour, wheat malt, sugar, and oil. It has a compressed structure with light brown colour. The reliable and precise history of Sohan is attributed to the Qajar era. It was a kind of Halva (from 1289 to 1290, when the Aqiq courtyard of Holy Shrine Hazrat Masoume (PBUH) was opened). So, the elders and big shots of Qom began to hold the splendid ceremony. Because of the security issues, Naser Al-din Shah sent his deputy to Qom. During holding the ceremony each of the elders and big shots of Qom gave the gifts to the deputy _such as the handicraft_ and it was a custom so as to show their respect and veneration. Meanwhile, one of the elders gave Samanou which was compound with sugar. When the deputy ate it, he became delighted and said that this Samanou digested my food like a “file” _in Persian it means “Sohan”. Then, he wanted to take some Sohan to the King. Since then, this Halva has been called “Sohan” and, thereafter, the production and the consumption of Sohan began. In early days, it was the special food for the aristocrats and nobles.
