Prepared in 25 minutes or less with spice, oh so nice!
Preheat oven to 400°F.
Prepare spiced cocoa rub by combining white peppercorns and coriander in a medium saucepan over medium heat.
Toast white peppercorns and coriander seeds until they begin to pop. Remove from heat and grind to fine powder in a spice mill or coffee grinder. Mix the ground pepper and coriander with remaining spices, cocoa and salt in a small bowl.
Rub with your fingers the prepared pork tenderloins with a generous amount of the spiced cocoa rub.
Heat the olive oil in a large sauté pan over medium high heat until hot but not smoking. Sear each tenderloin on all sides until a rich brown color, approximately 2 minutes on each side.
Remove tenderloins from heat and finish in the pre-heated oven for 10 minutes or until cooked through.
Let the tenderloins rest out of the oven for at least 10 minutes before carving into slices and serving on a platter. Serves 4.
