Dahi Puri is a popular variation of pani puri where the crispy puris are filled with a mixture of mashed potatoes, chickpeas, and spices, and then topped with sweetened yogurt, tamarind chutney, and sev (crispy chickpea flour noodles). The combination of tangy yogurt, sweet chutney, and crunchy puris makes Dahi Puri a delightful and refreshing snack.
