Place all sauce ingredients in a small saucepan. Heat, and simmer for 5 minutes, stirring often.
Preheat grill to medium-high. Oil grill so corn does not stick. FYI--I use a small spray bottle or a Misto especially for the grill. I also have another plastic spray bottle with water to extinguish any flame flare-ups.
Baste corn with sauce and cook for 3-5 minutes, or until the sauce has caramelized. Baste top of corn and turn. Cook for 3-5 minutes as before.
Remove from grill and serve immediately. Leftover sauce may be stored covered in the refrigerator -OR- served along with the corn for additional dipping.
