Dera Ismail Khan Sohan Halwa originated in the mid 19th century when Haji Abdul Rehman introduced it in the Dera Ismail Khan region of Pakistan. The unique sweet, prepared by roasting wheat flour in ghee and adding sugar, gained popularity for its distinctive taste and texture. The recipe became a closely guarded family secret, and the halwa is known for its inclusion of nuts like almonds and pistachios. Over time, it has become a cultural symbol of the region and a popular gift during celebrations.
