For the puris, I took 2 cups of flour and kneaded it into a stiff dough adding a little water at a time. Rest it for 5 minutes and roll out puris and fry in hot oil.
For potato podimas/ potato bhaji, boil 5 big potatoes, peel and mash them. Heat oil in a pan, add a tsp of mustard/jeera and let it splutter. Add a chopped onion, 2 chopped green chillies and fry till translucent. Add a chopped tomato and fry for a minute. Add water, salt, red chilli powder, turmeric powder and a spoon of pav bhaji masala and let the tomatoes turn soft. Add the mashed potato and allow it to cook for a few minutes. Garnish with coriander leaves.
