Margarita Chicken

1/2 cup gold tequila
1/2 cup triple sec
1 cup freshly squeezed lime juice (5 to 6 limes)
1/2 cup freshly squeezed orange juice (2 oranges)
1 tablespoon chili powder
1 tablespoon crushed red pepper (chili flakes)
1 tablespoon minced fresh jalapeno pepper (1 pepper seeded)
1 tablespoon minced fresh garlic (3 cloves)
2 teaspoons kosher salt
1 teaspoon freshly ground black pepper
3 whole (6 split) boneless chicken breasts, skin on

Combine all ingredients in a large bowl or ziplock bag. Refrigerate overnight.
Heat a grill and brush the rack with oil to prevent the chicken from sticking. Remove the chicken breasts from the marinade and grill them skin-side down for about 5 minutes, until nicely browned. Turn the chicken and cook for another 10 minutes, until just cooked through. Remove from the grill to a plate. Cover tightly and allow to rest for 5 minutes. Serve hot or at room temperature.
