Aloo Tikki Pani Puri is a fusion of two popular Indian snacks - aloo tikki and pani puri. In this recipe, the puris are filled with aloo tikki, which is a spiced potato patty. The aloo tikki is then topped with the usual pani, tamarind chutney, and garnishes. This combination of flavors and textures creates a unique and delicious twist on the traditional pani puri.
