History
Rogan josh came from Persia, and some argue that is where the name comes from, as rogan means "clarified butter" in Persian, and josh means "intense heat". Others say that the red color specific to the Kashmiri version of the dish gave rogan josh its name, as rogan means "red" in Kashmiri and gosht is a term for lamb ("josh" being the Anglicized version of the word).
