Place each ear of corn on a piece of foil.
Brush olive oil on each ear of corn and lightly sprinkle all sides of corn with sea salt.
Wrap foil tightly around corn.
Pre-heat the grill to medium heat and place all 6 ears of corn on the grill grates.
Close lid and cook for 15 to 20 minutes or until the corn on the cob can easily be pierced with a fork.
Turn often while the corn is cooking to prevent burning the corn cob.
While the corn is cooking, in a small bowl, mix together the ingredients for the crema.
When the corn is done cooking, carefully remove the foil.
Lightly brush each ear of corn with Mexican Cream Sauce mixture and sprinkle additional chipotle chili powder, cotija cheese, fresh parsley and fresh lime juice over each ear of corn.
Serve hot.
