Kottu, or Kottu Roti is a Sri Lankan dish, made from a Sri Lankan type of bread called Godamba Roti, and vegetables, egg, or meat, and various spices. An optional spicy gravy is usually served with a kottu rotti. A hot kottu is generally eaten as a dinner meal. The common varieties include beef and chicken as well as egg and vegetable Kottus made for vegetarians.
It is traditional to make the kottu on a heated iron sheet, used specifically for the purpose, and the kottu is chopped and mixed using two blunt metal blades. This clashing of metal on metal creates a very distinctive sound, and the beat of kottu being prepared can be heard rising up from any small roadside restaurant in Sri Lanka.
