In a wide and shallow bowl or platter, add grated cotija cheese, mayonnaise, sour cream, Tajin™, and minced garlic.
Stir together until well combined.
Refrigerate while you prepare your corn.
Cook your corn. You can either grill your corn, prepare it on the stovetop, or bake it in the oven.
Once the corn is cooked, remove the coating you made earlier from the fridge. Using a silicone brush or fork, spread a layer of the coating all over an ear of corn.
Sprinkle grated cotija cheese and Tajin™ all over the ear of corn, to taste.
Repeat until all ears of corn have been prepared with the coating and topped with grated cotija cheese and Tajin™. Cut up a lime to serve alongside the Elotes. Enjoy!
