Shuck and silk the corn and give it a good washing. Let the corn drain and then coat with a light coating of olive oil.
In a small bowl, mix 1 stick softened butter, a few shakes of salt, a few grinds of black pepper and 1/4 teaspoon granulated garlic.
Place the corn on a pre-heated grill over medium high heat and let the corn cook about 10 minutes, turning the corn with tongs as the corn cooks.
Remove from the grill, place on a serving tray, and brush on the softened garlic butter. Top with freshly grated lime zest and serve immediately.
