The original recipe didn't use sugar at all — it relied on angebin, a sweet secretion left by insects feeding on a local tamarisk shrub near Isfahan.
Whipped egg whites are combined with sugar (traditionally angebin), rosewater, and whole pistachios or almonds, then set into a soft, chewy nougat and cut into squares dusted with powdered sugar. Isfahan's confectionery shops have sold it as the city's defining souvenir sweet for more than 450 years.
