Heat your grill to roughly 400 degrees F.
After rinsing the corn, take each corn on the cob and rub it down with the stick of butter, season with salt and pepper and wrap in aluminum foil.
Place the corn on the grill and grill for roughly 15 minutes, turning the cobs 1/4 turn every 3 minutes. You can also roast the corn in the oven on 425 for 20-25 minutes or until corn is soft.
Mix the topping sauce by stirring together theĀ a Sour Cream, mayonnaise, cotija cheese, garlic, lime zest and juice, and cilantro. Add more salt & pepper to taste if need be.
Generously top each corn cob with the cheese mixture, sprinkle with a bit of Rajiv seasoning, and top with a bit of extra cotija cheese and cilantro.
