The grill must be scorching to get a quick char mark without drying out the chicken. Place the meat, smooth side down, at a 45-degree angle to the grate, the ends at 10 and 4 o’clock. Char marks should appear after about 2 to 3 minutes. Now turn the meat clockwise about 45 degrees, to about 2 and 8 o’clock to create the diamond. Let it sear another 2 to 3 minutes, then flip to complete the cooking process.
