Cocoa-Chile-Rubbed Grilled Pork Tenderloin

1. 1Place all of the ingredients in a small bowl and mix to combine; set aside.

For the tenderloins:

1. 1Trim the pork of any silver skin and pat it dry with paper towels. Using your hands, rub the tenderloins all over with the oil, sprinkle them with all of the spice mixture, and rub until evenly coated. Set aside at room temperature for 30 minutes or cover and refrigerate for up to 24 hours.
2. 2Heat a gas or charcoal grill to medium (about 350°F to 450°F). If the tenderloins have been refrigerated, let them sit at room temperature for at least 30 minutes before grilling.
3. 3Place the tenderloins on the grill. Cover the grill and cook, turning every 5 minutes, until the tenderloins are browned all over and an instant-read thermometer inserted into the thickest part registers 145°F to 150°F, about 20 to 30 minutes.
4. 4Transfer the tenderloins to a cutting board and let them rest for 5 to 10 minutes. Cut crosswise into 1/2-inch-thick slices and serve.
