Nogha is a variety of the widely popular Iranian nougat called gaz. Originally, Iranian nougat was made with an unusual exudate of an insect inhabiting wild tamarisk trees. The solid exudate was melted and sieved to create the rich and sweet base of the nougat.

Today, the original method is usually replaced with a more available mixture of sugar and beaten egg whites, which produces a product similar in texture and flavor to the original gaz. Nogha is one of the numerous varieties found in the country, typically eaten in the Azerbaijan-Iran region.

It is typically made with chopped walnuts, unlike other types which mainly use pistachios and almonds. Nogha gaz is usually spread between two thin wafers and is often cut into larger rectangular shapes. The sweet taste, sticky texture, and crunchy walnuts make nogha an immensely popular confectionery, eaten as a dessert or a sweet snack.

Because of its beautiful visual appearance, it is often given as a gift or a traditional and authentic Iranian souvenir.
