Gaz is an Iranian nougat originated in Isfahan. It is widely known as Persian Nougat in American and European countries.
The traditional way to serve gaz is in round pieces that are about 2 inches in diameter and up to 1/2-inch thick. A modern presentation is to serve the nougat cut into smaller rectangles.Depending on the ingredients mixed in, gaz can have a subtle rose flavor, a nutty taste, or a savory and pungent profile. It can be white, or it can become another color because of the addition of spices (such as saffron) or nuts.
