Remove the shell of corn from the kernel, Remove it completely or else you can hold them together in the bottom. Show the corn in direct flame. Rotate and show in all the sides evenly. You may also grill the corn instead of showing them in direct flame. The idea is to give the corn a smoked flavor.
The corn will get grilled with the charred mark. Continue for 5 to 7 mins or till you get light charred marks on the corn. Make sure you rotate and show the corn evenly on all the sides of the corn. Set the corn aside
In a mixing bowl add in the Mayonaise and tomato ketchup.
Mix well until they are homogeneous.
Now remove the corn kernels and add to the mayo and ketchup mixture.
Now dollop in the smoked corn into the taco shells or tortillas. I am using my homemade flour tortillas.
Garnish with some sliced or pickled onions and cilantro and serve.
