In a medium-size nonstick or cast-iron sauté pan over medium-low heat, add peppercorns, star anise, cloves, and fennel. Swirl in the pan and toast gently until fragrances are released, 2 to 3 minutes. Transfer to a plate and let cool. Place in a spice grinder and pulse until well ground. Grate cinnamon into mix, add sugar, and stir well to incorporate.

Heat your grill to medium-high, and oil the grates lightly.

Rub chicken thoroughly with oil. Then rub it thoroughly with spice mixture. Place chicken on the grill, skin side down. Season with salt. Cover the grill with the lid and let cook 15 minutes. Turn chicken and season with salt. Cover the grill again and cook 15 minutes, or until fully cooked through. Serve with Gingery Cole Slaw (recipe below).
