Afghan bread, or Naan-e Afghani (Persian:نان افغانی), is the national bread of Afghanistan. The bread is oval or rectangular and baked in a tandoor, a cylindrical oven that is the primary cooking equipment of the sub-continental region. The Afghan version of the tandoor sits above ground and is made of bricks, which are heated to cook the bread. The bread, also known as naan, is shaped and then stuck to the interior wall of the oven to bake.
