Put thick yogurt in a deep bowl. Add black salt, salt to taste, cumin powder, raita/mixed masala and whisk it well until curd becomes smooth and creamy.
Take another deep bowl and put chopped and unpeeled cucumber, chopped tomatoes, chopped potatoes and ½ of the curd mixture. Mix it until well combined.
Now place the veggies mixture in a serving tray and spread it evenly all around.
At the time of serving, sprinkle cornflakes on the spread mixture.
Now pour the remaining yogurt mixture, tamarind chutney, coriander chutney, sprinkle some red chana (I forgot to mix chana with vegetable mixture so I have sprinkle it from top).
Lastly garnish it with some pomegranate seeds, sprinkle some raita masala and finally end it with freshly chopped coriander leaves and sev.
Cornflakes chaat is ready to serve.

Notes
Sprinkle cornflakes at the time of serving only otherwise cornflakes will not be crunchy and will become too soggy.
