Stir together in a small bowl all ingredients listed from smoked paprika through the salt. This will make your blackened seasoning and is more than the 1 Tablespoon needed, but the remainder can be stored to use in another dish.
Put oil in a 10-12 inch cast iron skillet and heat over medium high until a drop of water "dances" on the surface.
Add corn and then sprinkle with 1 Tablespoon of the blackened seasoning.
Pat down lightly with a spatula and allow to cook for about 2 minutes.
Stir to allow corn kernels on top to get to surface of skillet and cook an additional 2 minutes (approximately) or until desired char is reached.
Stir in melted butter and garnish if desired before serving.
Notes
Fresh corn will need to be cut from the cob with a sharp knife. 3-4 ears of corn will yield about 2.5-3 cups of corn kernels.
If using frozen corn, thaw on paper towels and pat to get out excess moisture before cooking.
A cast iron skillet will produce the best results.
In lieu of homemade seasonings you can substitute 2 teaspoons of ready-made blackening seasoning.
Suggested garnishes are chopped chives, bacon bits and additional coarsley ground black pepper.
