To begin making the Chatpata Masala Chips Recipe, first prep all the ingredients and keep them ready.

For making the sour cream, in a bowl, combine heavy cream, lemon juice, and a pinch of salt. Stir well and let it sit at room temperature for about 2 hours until it thickens slightly. Once thickened, stir again and refrigerate until ready to use. Ideally made the previous day and refrigerated.

Finely chop the onion, green chilies, tomato, and coriander leaves. Toss it along with chaat masala and keep it aside. If you want a milder heat level, reduce the quantity of green chilies or remove the seeds. 

Spread the plain salted potato chips evenly on a large serving plate or tray.

Sprinkle the chopped onions, tomatoes, green chilies, and fresh coriander evenly over the potato chips.

Generously sprinkle a little more chaat masala over the chips and toppings. Add red chili powder for extra heat, if desired. You can also sprinkle a pinch of black salt for added flavor.

Drizzle or dollop the homemade sour cream generously over the masala chips.

Squeeze fresh lemon juice over the masala chips for a tangy kick.

Serve the Chatpata Masala Chips fresh to maintain the crunch of the chips and the freshness of the toppings. Enjoy with a cold drink or as a party snack!

Tips:You can add some sev or crushed papdi for extra crunch. For a healthier twist, use baked or air-fried chips.
