Trim ends off of eight large ears of unhusked corn. Remove about half of the husks. Push the remaining husks aside and remove corn silk. Replace husks and tie into place. Put ears on a rack in a large covered kettle. Add 2 cups water, cover and steam for 20 minutes or until corn is tender. Remove husks. Heat 1/2 cup butter and 2-3 teaspoons of chili powder; brush on corn just before serving.
