10 puris [flat ones]
75g potato 
50g onion
1 tbsp mithi chutney
1 tbsp cilantro chutney (skip the peanuts)
1 tbsp wet lasan chutney
squeeze of lemon 
1 cup sev 
handful cilantro finely chopped 

1. Wash potato thoroughly. Either place in pressure cooker with the skin on for 3 whistles, or peel and boil. I prefer the pressure cooker method because it assures minimus water retention. When cool to handle, peel and dice.

2. Prepare the chutneys. Then, mix them all together in a bowl. Add a couple tablespoons of water. You want the chutney mixture to be slightly runnier than ketchup but not too watery.

3. Assemble: First, place the puris on a plate. Next, put the potatoes on top. Then the onions. Then about ¼ to ½ tsp chutney mix. Then a big squeeze of lemon. Lastly, add the sev generously and sprinkle the cilantro. One bite puri, so open wide!

4. Pairs well with other chaat items - pani puri, bhel, dahi puri, ragda pattis
