If you get a package containing two tenderloins of uneven size, you may have to cook the larger one a little longer than the smaller one. Prepare all the sauce ingredients before grilling the pork, then cook it while the pork stands.
Cooks' note:
Tenderloins can be cooked in a hot lightly oiled well-seasoned large (2-burner) ridged grill pan over moderately high heat, turning over occasionally, until well browned, about 10 minutes, then roasted in middle of a preheated 400°F oven until thermometer registers 150°F, about 10 minutes more. Let stand, loosely covered, 10 minutes.
