Lavash is a thin flatbread usually leavened, traditionally baked in a tandoor or on a sajj, and common to the cuisines of South Caucasus, West Asia, and the areas surrounding the Caspian Sea. Lavash is one of the most widespread types of bread in Armenia, Iran and Turkey. The traditional recipe can be adapted to the modern kitchen by using a griddle or wok instead of the tonir.

A flatbread is bread made usually with flour; water, milk, yogurt, or other liquid; and salt, and then thoroughly rolled into flattened dough. Many flatbreads are unleavened, although some are leavened, such as pita bread.
