Though the countries in the Persian culinary region are home to diverse religions, cultures, languages, and politics, they are linked by beguiling food traditions and a love for the fresh and the tart. Color and spark come from ripe red pomegranates, golden saffron threads, and the fresh herbs served at every meal. Grilled kebabs, barbari breads, pilafs, and brightly colored condiments are everyday fare, as are rich soup-stews called ash and alluring sweets like rose water pudding and date-nut halvah.
