Close grill. Grill at about 375° for 20 minutes [depending upon meat thickness] flipping chicken occasionally. Don't burn or char your chicken just yet but, you do want to see some grill or score marks as pictured below. Keep fruit rinds on top of your chicken. ° Add the remainder of your marinade to your chicken breasts during this time. Remember, not only are you [not] brining this chicken for added moisture - you're also grilling this meat over open flames. With that, you'll want all of the moisture you can get in this chicken!
