In a large cast iron skillet, melt butter over medium high heat.
Add the corn, sea salt, black pepper, garlic powder and cayenne and stir to coat the corn kernels.
Allow the corn to fry, uncovered for about 3-4 minutes before stirring again. The desired outcome is to have some slightly charred corn kernels but not burnt. If the corn is burning, turn down the heat slightly.
Continue to sauté uncovered for a total of 10 minutes or until some of the corn is slightly browning and hot.
Serve immediately.
Skillet fried corn can be stored in the refrigerator for up to 4 days.
