Peel back the corn husks carefully, without breaking them off and discard the silks. Fold the husks back into place and tie the ends together with the strips of outer husk or kitchen string.

Combine the corn in large bowls with cold water to cover and let it soak for 10 minutes. Drain the corn and grill it on a rack set 5-6 inches over glowing coals, turning it occasionally, for 15 minutes. Serve the corn with the sage butter. Serves 6.
