that has been produced in Isfahan city for many centuries. It contains the sugary extract of the root of Tamarix.
A special kind of Gaz is referred to as Nogha in Persian. Nogha is almost exclusively made with walnuts instead of pistachios & almonds which are usual for other types of Gaz. The making of Nogha is very much the same as any other Gaz. The difference is that Nogha is usually spread between two very thin layers of wafers and cut into 10x5x5cm sections which are larger than ordinary Gaz cubes.
