Creating grilled street corn is a straightforward process that even beginners can master. Follow these easy steps to achieve amazing results:

1. Preheat the Grill: Heat your grill to medium-high heat for optimal cooking temperature.
2. Prep Corn: Husk the corn and remove all silk. Rinse under cold water and pat dry.
3. Skewer the Corn (Optional): If desired, skewer the corn with long grill skewers to make turning easier.
4. Grill the Corn: Place the corn directly on the grill and cook for approximately 15-20 minutes. Turn every 5 minutes to ensure even charring.
5. Make the Sauce: In a bowl, mix together mayonnaise, sour cream or Greek yogurt, lime juice, garlic powder, and salt until well combined.
6. Add Cheese and Spice: Once the corn is grilled to a golden brown, remove it from the grill. Generously spread the sauce over the corn and sprinkle with cotija cheese and chili powder.
7. Garnish: Add fresh cilantro on top for a burst of color and flavor.
8. Serve: Offer lime wedges on the side for an extra citrusy kick.

Following these simple instructions will lead you to create the most delicious grilled street corn that your family and friends will love.
