Puttu is cylindrical in shape and is made traditionally  of rice flour and coconut. This rice flour dough is layered with grated coconut and steamed in a hollow bamboo or Puttu maker called "Puttu chemb" or Putti Kutti, a steamer which is cylindrical in shape. It is usually eaten with sugar or with mashed ripe or steamed bananas or with a spicy curry made of Kadala . Usually, the main sidedish served along with Puttu is Kadala Curry. This is often served for both breakfast and evening tea.
