I found this wonderful recipe courtesy of Style Blueprint Nashville.  Images and text courtesy of the site.  Check this out. I am headed to the Mexican grocery to get supplies!
I experienced Mexican street corn for the first time at 
Mas Tacos,
 a little slice of Mexican food heaven in East Nashville. Wow. I was 
obsessed then and I remain obsessed, still. Be prepared when you go: 
they only take cash, it takes a while to get your food and there are not
 many seats.  But, if you have an adventurous spirit, you will be 
blessed — yes, blessed — with some seriously tasty food.  All the items I
 sampled from the menu stood out, but the winner, hands down, was the 
Mexican Street Corn.

So, what’s a girl with a can-do attitude and a fearless culinary spirit to do?  Recreate the dish, of course.
My first two attempts did not go well.  This is when I realized that I
 needed to scrap the American substitutes and go authentic for 
ingredients.
The 
Supermercado
 at 6321 Charlotte Pike provided exactly what I needed: crema (Mexican 
crème fraîche) and Cojita cheese (which is similar to the flavor of mild
 feta mixed with Parmesan, with the consistency of pizza Parmesan.) 
There are many types of crema to choose from, but I prefer the crema 
from Guatemala.  And as an aside, while shopping, we picked up the best 
corn tortillas I have ever tasted: La Providencia brand – 36 for just 
$.99!
Mexican Street Corn 
Ingredients (for six servings):
- 6 ears of corn
 
- Crema
 
- Cojita cheese
 
- Mexican chili powder
 
- Salt
 
- Limes
 
Directions:
Grill the corn, either directly on the grate or wrapped in foil, for about 10 minutes. (Grilling makes a difference, trust me.)
Use a BBQ sauce brush to coat the corn with crema.  Next, roll it in 
the Cojita cheese and sprinkle with Mexican chili powder and a little 
salt.  Then, squeeze the juice from half a lime over the corn and wrap 
it in foil.  Eat.

Start with hot cooked corn, preferably grilled, but boil if you must.

Sprinkle with some Mexican chili powder and 
salt. Squeeze fresh lime juice over each ear. For authenticity, wrap 
each ear in foil to serve.

If you want to cut off, that is fine. I'm 
thinking some chopped cilantro and fresh jalapenos might make a great 
addition when served this way. And butter. When does butter not make 
everything better?!

This corn makes an excellent pairing with Tortilla Soup. Or, for 
simplicity, cut up some heirloom tomatoes, sprinkle with sea salt and 
enjoy a perfect vegetarian meal.
