Puttu (pronounced [ˈputtu]), or pittu (Malayalam: പുട്ട്; Tamil: புட்டு; Kannada: ಪುಟ್ಟು; Sinhala: පිට්ටු), is a breakfast dish eaten in Kerala, parts of Karnataka, and Sri Lanka. Puttu means "portioned" in Malayalam. It is made of steamed cylinders of ground rice layered with coconut, often with a sweet or savory filling on the inside. It is highly popular in the Indian state of Kerala as well as in many areas of Sri Lanka, where it is also known as pittu. Puttu is served with side dishes such as palm sugar or chickpea curry or banana. In Bhatkal Puttu is served with side dishes such as ghee and sugar or Paya.
Puttu principally consists of coarsely ground rice, grated coconut, little salt and water. It is often spiced with cumin, but may have other spices. The Sri Lankan variant is usually made with wheat flour or red rice-flour without cumin whereas the Bhatkal recipes have plain coconut or masala variant made with mutton or shrimp flavoured grated coconut. In Bangladesh, the outside is made of a mixture of rice flour and ground moong dal, while the filling is a mixture of coconut flakes and a type of caramelized sugar that is similar to dulce de leche. 
Puttu is made by slowly adding water to ground rice until the correct texture is achieved. It is then spiced, formed and steamed with layers of grated coconut.
Puttu is generally cooked in a metal puttu kutti vessel with two sections. The lower section holds water and the upper section holds the puttu — where the rice mixture is inserted with layers of grated coconut. Perforated lids separate the sections to allow the steam to pass between them.
A number of alternative cooking vessels are used, such as traditional vessels where a perforated coconut shell is attached to a section of bamboo, or a chiratta puttu made of a coconut shell or of metal shaped similarly to a coconut shell.
Puttu is often served along with gravies, like fish curry, chicken curry or kadala (chickpea) curry, and papadum. Also plantain, jackfruit, mango or banana is commonly served with it. In southern kerala people eat puttu accompanied by sweet black coffee. In Tamil Nadu it is served with grated coconut with jaggery made of palm or sugar cane, or with sweetened coconut milk. In Sri Lanka, pittu is usually accompanied with tripe curry, fish or a meat curry, coconut milk and a sambol.
Some variations of puttu use other grains such as wheat flour, tapioca and corn flour. The layered filling of coconut can be replaced by other foods, such as egg curry or banana. Puttu prepared in a ball shape are called manipputtu. Puttu can also be made using bamboo rice
Puttu is also very common in Mauritius. It is usually sold by hawkers and is served as a snack. It is often misspelled poutou and should be spelled putu in Mauritian creole. The ingredients are the same; rice flour, sugar and desiccated coconut but cooked in metal cylinders.
In Maritime Southeast Asia, there are numerous similar dessert dishes known as kue putu in Indonesian, putu bambu in Malay, and puto bumbóng in Tagalog. They vary by preparation and ingredients but are also steamed in bamboo tubes and are served with sugar and grated coconut.
In Indonesia, kue putu is characteristically green due to the use of pandan flavoring. It is commonly found being sold by traveling vendor carts together with klepon, which is actually ball-shaped kue putu.
In the Philippines, puto bumbong is deep purple in color due to the use of a unique rice variety called pirurutong. They are culturally significant as a common traditional Christmas dessert. Puto in the Philippines is also a general term for traditional steamed rice cakes.
In 2006, students of the Oriental school of Hotel Management in Wayanad in north Kerala made a 10 foot long puttu. They cooked the giant puttu in a specially designed 12 foot long aluminium mould, using 20 coconuts and 26 kg of powdered rice. It took about one and a half hours to cook.
