Cook the corn: Boil or steam corn until tender, about 4–6 minutes if using fresh or frozen.
Drain well. If using canned, rinse and drain.
Warm it up (optional): For a cozy version, heat a pan over medium, melt the butter or ghee, and toss in the corn for 1–2 minutes until glossy.
Add aromatics: Transfer the corn to a mixing bowl. Add onion, tomato, green chili, and cilantro.
If using boiled potato, fold it in gently.
Season boldly: Sprinkle chaat masala, roasted cumin powder, red chili powder, and black salt. Start small; you can always add more.
Brighten with lime: Squeeze in lime juice and toss well. Taste and adjust salt, heat, and tang.
Finish with crunch: Top with sev or crushed papdi just before serving so it stays crisp.
Add pomegranate if you like a sweet pop.
Serve: Enjoy warm right away, or chill for 15–20 minutes for a refreshing, picnic-style snack.
