Heat a large grill pan over medium-high heat. Coat pan with cooking spray. Add corn to pan; cook 8 minutes, turning frequently.
Place butter in a small microwave-safe bowl. Microwave at HIGH 30 seconds or until butter melts. Stir in chile powder, rind, pepper, and salt. Brush butter mixture over corn.
This is a simple way to add an extra kick to your corn on the cobb. Check out my post here: http://www.icancookthat.org/2011/07/grilled-corn-with-chipotle-lime-butter.html
