Combine butter and TABASCO® Sauce in a small bowl and mix well.
Peel one side of corn husk away from cob without removing completely, and loosen remaining husk; do not remove silk. Brush butter mixture over kernels and smooth back husk to original shape.
Prepare a charcoal fire, letting coals burn until they are covered with gray ash and are medium hot. Place corn directly onto coals and cover grill with lid or a foil tent. Cook 2 to 3 minutes per side. Outside of husk will be charred.
