Puliseri, or Pulissery, is a yoghurt curry with simple spicing and thickened slightly with rice flour, designed to eat over rice. It can also be eaten as a soup, but this is non-traditional.
Pulissery is often associated with Kerala on the West coast of India, where it is also often cooked with vegetables. This recipe is from its neighbour, Tamil Nadu, and is kept simple without any additions.
The recipe is another from Meenakshi Ammal’s Cook and See books, full of traditional Tamil recipes. This one is from a recipe in Volume 3, and she calls it the Raw Variety of Pulissery.
