Begin by preheating your grill to medium-high heat. This will create the perfect environment for charring the corn.
Once the grill is ready, place the husked corn on the grill grates. Grill the corn for about 10-12 minutes, turning it every few minutes until the exterior is nicely charred and caramelized. Once grilled, remove the corn from the grill and set it aside to cool slightly.
After the corn has cooled enough to handle, carefully cut the kernels off the cobs using a sharp knife. Transfer the kernels to a large mixing bowl.
Into the bowl with the corn, add the halved cherry tomatoes, diced red onion, crumbled feta cheese, and chopped cilantro. Stir the ingredients gently to combine them.
In a separate small bowl, whisk together the mayonnaise, sour cream, freshly squeezed lime juice, chili powder, salt, and pepper until you achieve a smooth and creamy dressing.
Drizzle the dressing over the corn mixture. Using a spatula or wooden spoon, gently toss everything together to ensure all ingredients are evenly coated with the dressing.
Take a moment to taste the salad and adjust the seasoning as necessary. Feel free to add more lime juice, salt, or chili powder to suit your taste preferences.
You can serve the salad immediately for a fresh experience, or for an even richer flavor, chill it in the refrigerator for about 30 minutes to allow the flavors to meld beautifully.
Notes
Serve chilled for enhanced flavor. Garnish with cilantro and lime wedges.
