To begin making the Aam Panna Pani Puri Recipe, we will first make the Aam Panna Pani. 

In a pressure cooker, peel the raw mango and add the whole raw mango along with 1/2 cup of water and pressure cook for 4 whistles. It has to be cooked until they become soft and tender. Turn off the flame. Allow the pressure to release naturally.  

Open the lid, drain the water, transfer the mangoes into a bowl and allow the mangoes to cool . Extract the pulp from the cooked raw mango and discard the seed. You will be left with the cooked raw mango pulp. 

In the bowl with the cooked raw mango pulp, add in the mint leaves, cumin powder, black salt , black pepper powder and sugar. 

Transfer this mixture into a mixer jar and grind into a smooth puree.

Transfer the aam panna into a serving bowl, add 1 cup of water and mix well. Check the taste and spices and adjust accordingly. Chill the Aam Panna Pani in the refrigerator.

For the Pani Puri filling, in a mixing bowl, mash the potatoes, add the green moong sprouts and the dry masalas- chaat masala, cumin powder and red chilli powder. Mix well.  Check the taste of the aloo masala and adjust salt or seasoning if required.
