Combine rava, wheat flour, maida, baking soda and salt, add water little by little to make a stiff dough like how we make for puris.Allow it to rest for atleast 15-30mins.

Knead the dough once again and pinch equal sized lemon sized balls.

Using the chapathi roller, roll out thin rotis and cut with a lid or cookie cutter as a small round puris.

Heat oil in a kadai(it shouldnt be piping hot) slide 3-4 puris at a time and using the laddle press in the center and along the edges to make the puris puff up.

Flip over to other side and cook to golden brown on both sides.Drain in a tissue paper.Cool and store in an air tight container and use when required.

Soak the tamarind in ½ cup of water for approximately 1 hour.

Strain out all the pulp through a sieve.

Combine this pulp with the remaining ingredients(chat masala/amchur powder, roasted jeera powder,mint,coriander leaves) except salt and grind it to a fine paste.

Transfer the paste into a large bowl and combine with the 2 cups of water, salt and mix well.

Chill for at least an hours after making for the flavours to blend well.

Mash the boiled potatoes, mix turmeric, chilli powder and salt, Keep aside.

Crack a small hole in the centre of each puri. Drop a teaspoon of mashed potatoes, then a teaspoon of green gram , then add mint chutney, sweet chutney and then chopped onion.

Top it up with sev and pour the prepared pani.
