Preheat oven to 425ºF.

ROAST: Season pork tenderloin with salt and pepper. In preheated oven, roast in shallow roasting pan for 20 to 30 minutes, until internal temperature, measured with a meat thermometer, reads 155 to 160ºF. Pour glaze evenly over tenderloins during last 10 minutes of roasting time. Serve tenderloins sliced.

GLAZE: Drain cherries, reserving juice. To this, add enough cherry-flavored juice making a total of 1 cup juice. In a small bowl, stir cornstarch into 2 tablespoons juice. In small saucepan, combine cornstarch mixture with remaining juice, cherries, brown sugar and cranberries. Cook, stirring, until mixture boils and thickens; stir in mustard.
