Gaz is a Persian confection known for its chewy texture and delicate sweetness, primarily produced in the city of Isfahan. It belongs to the broader family of nougat confections and is often considered a symbol of Isfahani hospitality and craftsmanship.
Gaz is typically made by combining a syrup derived from the sap of a desert plant called angebīn (Tamarisk manna) or, in more modern recipes, glucose syrup, with egg whites beaten into a stiff foam. The history of gaz dates back several centuries, when the sap collected in the Iranian plateau was blended with local ingredients to create a sweet that could be stored for long periods.
The preparation of gaz involves heating the syrup to a precise temperature and then slowly folding it into the whipped egg whites to create a smooth, elastic mass. This mixture is stirred constantly to prevent sticking and to achieve the desired density and gloss.
Once the nuts and flavorings are incorporated, the nougat is spread into molds dusted with flour or starch to prevent sticking and left to cool. When firm, it is cut into small rectangular or diamond-shaped pieces and sometimes wrapped in edible rice paper to keep the surface from becoming tacky.
Gaz is traditionally served alongside tea and is popular as a gift during holidays and family gatherings. The flavor combines the floral notes of rosewater with the richness of nuts and the gentle sweetness of the manna syrup, which sets it apart from European nougat varieties.
