Preheat your grill to high. Brush the corn with a thin layer of olive oil. Once the grill is very hot, about 10 minutes, arrange the corn on the grates and cook until charred to your liking.
Turn the corn often to cook and char all sides. This should take about 10 minutes in total.
Remove the corn from the grill. If you’d like to add the optional lime and Aleppo pepper, immediately run the cut lime all over and season with a sprinkle of Aleppo pepper. Either way, finish with a pinch of salt and serve immediately. Enjoy!
