Gaz
Gaz is the sweet every visitor carries home from Isfahan, sold in round tins of floury, pistachio-studded pieces at the bazaar near Naqsh-e Jahan square and handed round with tea at Nowruz. Isfahan's confectioners make it with angebin, a sap gathered from tamarisk shrubs, which is hard to find abroad; this home version whips egg white into a hot sugar and glucose syrup to get the same soft, chewy, white nougat, scented with rosewater. A common mistake is pulling the syrup off the heat too soon: below 140 °C the gaz stays sticky and never sets. Chef's tip: cut it with a knife dipped in hot water and toss the pieces straight into flour so they don't stick to each other.
