Panipuri is a street snack that is extremely popular in India, Bangladesh, Pakistan, and Nepal. Small in size, it consists of a hollow puri that is fried until crispy, then stuffed with a combination of flavored water called pani, tamarind chutney, chaat masala, potatoes, onions, hot chillis, and chickpeas. In North India, panipuri is known as golgappa, gol referring to the crispy shell, and gappa referring to the eating process, since these small snacks are typically eaten one at a time. It is believed that panipuri originated in Uttar Pradesh and gradually spread in popularity throughout the country and outside of it.
