We soak the ears whole in water for ~1 hour prior to placing on the grill. I place on the top section of the gas grill till the husk start to dry out and blacken. This is usually 30-40 minutes on a low setting. Using the gas grill allows me to cook the steaks, ribs or what ever on the mesquite wood grill. After cooking the ears, cut the ear ~1" above the stalk and squeeze out the cooked ear silk free.
We do this. Add some Old Bay seasoning to it after it's been cooked for something a little different.
