Rice Pori (also called Nel Pori in Tamil) is puffed rice, made by heating rice grains until they expand and become light, crispy, and airy. It is commonly used in South Indian snacks and sweets, like Karthigai Pori or Pori Urundai, and is popular as a light, easy-to-digest food. Rice Pori can be eaten plain, spiced, or mixed with jaggery, and is often prepared during festivals and special occasions.
