Sangak is a plain, rectangular, or triangular Iranian whole wheat leavened flatbread.Its name consists of two parts: 'Sang' in Persian means stone or pebble and 'sangak' means little stone. The bread is baked on a bed of small river stones in an oven. There are, normally, two varieties of this bread offered at Iranian bakeries: the generic one which has no toppings; and the more expensive variety which is seed bread (this is, topped with poppy seeds and/or sesame seeds).
