Soak corn for atleast 30 minutes in cold water. Drain.
Heat grill to medium high. Cook corn on the grill until browned on all sides, rotating every few minutes. The corn is done when you pull back the husk and the kernels are tender.
If desired, you can place the shucked corn back onto the grill bare for more smoky flavor.
Combine the melted butter and fresh basil in a small bowl.
To serve, place the shucked grilled corn on a tray and pour the basil butter over the top.
