Tandirs are traditional pottery ovens used in Azerbaijan to make bread and sometimes meat and poultry. Today, masters mostly craft two types of tandirs: surface and underground ovens. The bread baked in tandirs is considered a key to longevity and is an integral part of the daily diets of the people of Azerbaijan. It can be stored for a long time and eaten over several days. Tandirs and bread baking are believed to promote solidarity. They embrace a large number of oral traditions, beliefs, rituals, cultural functions and meanings. The knowledge of tandir craftsmanship is transmitted within families through observation and practice. The baking knowledge is also passed on within families through oral communication and instruction. Young women and men from the same families observe, participate in and help with the baking process. Parents eagerly share the knowledge, beliefs and expressions about tandir and bread with their children, teaching them to treat the bread with respect. Baking in tandirs is a sort of ritual that strengthens social bonds and supports family and neighbourhood ties. Traditionally, communities offer bread to children and guests first. People believe that this brings prosperity to the household. Tandir-baked bread is also a source of livelihood.
