Fill your sink (or a large bucket) with water and soak corn with the husks on for about 5 minutes
Remove corn from the water and shake off excess
Heat your grill to medium-high heat. Lay the corn husks on the grill and close the lid. Turn the corn every 5 minutes for about 15-20 minutes or until the corn is cooked and tender. NOTE: you can also do this in an oven preheated to about 450 degrees F or underneath the broiler.
Let the corn cool for a few minutes and remove the husks.
In a food processor, combine, yogurt, sour cream, garlic, cilantro, lime juice and garlic and pulse until well blended.
Spread or drizzle the dressing on top of the corn. Sprinkle with paprika, cotija cheese and cilantro.
