Fried crispy puris 
Boiled potatoes 
Green chutney/water 
Ingredients:
Potatoes – 3 big cut into cubes
Dates Tamarind chutney – 1 cup
Coriander Mint chutney – 1 cup
Soaked and cooked green moong dal/black chick peas – 1/2 cup
Chat masala – 1/2 tsp
Dry mango powder/Jeera powder – 1/2 tsp
Sev (optional) – 1/4 cup
Preparation:
For Puris
Semolina/Rava – 1 cup
Soda bi carbonate – 3 to 4 pinches
All purpose flour/Maida – 1 tbsp
Soda water – 6 tbsp
Salt – 1/4 tsp
Oil – 1 tsp
Oil for deep frying
Preparation:
In a mixing bowl, add semolina, oil, baking soda and salt. With your fingers, mix the oil evenly with the semolina. Now, add maida/all purpose flour to this mixture.
Mix again very well so that the all purpose flour is mixed evenly. Add 3 tbsp soda water first. Mix again. Then add 1 tbsp soda water more and begin to knead the dough. The semolina absorbs water while kneading. Add water in parts while kneading.
Then add 3 tbsp more of the soda water and continue to knead. The kneading is very important in getting the perfect pani poori texture. The dough should not be too soft or too hard. If you make the dough soft, then add 1 to 3 tsp more of the sooji. If the dough looks hard, then add sprinkle some water and continue to knead.
Knead it again as the elasticity in the dough helps in rolling the dough without cracks and thinly. When rolling, the dough should roll easily without any cracks. Knead to a semi soft elastic dough and keep it in a bowl or pan.
Cover the dough with a moist kitchen towel or napkin and allow the dough to rest for 60 minutes.
After 60 minutes, knead the dough again. Divide the dough into 4 parts and knead out one part into a big circle. With a round cutter, make 5 to 6 small circles, cut it out and deep fry it in hot oil. The oil should be really hot while frying. Gently nudge each puri while it is dropped into the oil. This helps the puris to puff up easily. When it turns golden brown, flip it to the other side and cook. Remove when it turns golden brown on this side. Repeat this process for the other 3 parts of the dough.
When the puris cool down, store these puris in an airtight container.
Preparing the dal and the potatoes
Soak black chana dal or green moong dal in water for 4 to 5 hours. Pressure cook black chana dal with a pinch of salt for 2 -3 whistles. or if using green moong dal, boil it in a vessel with a pinch of salt and enough water. Keep it aside when cooked and water has been absorbed.
Cut the boiled potatoes into cubes and keep it aside. Sprinkle it with little chat masala and jeera powder. Add the boiled black chick peas or green moong to it and mix.
Assembling the puris
Keep the coriander mint chutney and tamarind chutney in a bowl, ready to serve (recipe below).
To serve, tap the puri gently at the centre lightly to make a half inch hole in it. Add about 1 teaspoon of the potato dal filling into the puri. Fill the puri with some tamarind dates chutney and coriander mint water and serve.
