To make ahead: The basting sauce (Step 1) and mustard sauce (Step 3) can be prepared and chilled up to 24 hours ahead.
Variation: Grilled Pork Roast: Prepare grill for indirect grilling. Test for medium-high heat above pan. Place the tenderloins on the grill rack over the drip pan. Brush some of the basting sauce over the tenderloins. Cover and grill for 30 minutes. Brush the tenderloins with additional basting sauce (discard any remaining sauce); sprinkle the tenderloins with sesame seeds. Cover and grill about 10 minutes more or until a thermometer inserted in the thickest part of each tenderloin registers 160 degrees F.
