A tava, tawa, tapa, saj, or saj tava is a flat or concave disc-shaped frying pan or griddle, usually made of cast iron, aluminum, or carbon steel. It may be enameled or given a non-stick surface. It is used in the cuisines of Central, West, and South Asia, and of the Caucasus, the Caribbean, and the Balkans. The large concave styles of tava, sometimes called a saj or sac tava, may be turned upside down for cooking a variety of flatbreads on the convex side. The concave side is used like a wok or frying pan.
