Wrap the bacon slices around the pork loin and secure with toothpicks.
Preheat a large skillet over medium-high heat, then add the pork loin.
Cook until golden brown on all sides, about 10 minutes, then place onto roasting pan.
Stir together honey, balsamic vinegar, red wine, onion, and rosemary in a small bowl; spread over pork loin.
Roast the pork loin in preheated oven for 15 minutes, then sprinkle with raisins.
Continue cooking until the internal temperature of the pork loin reaches 160 degrees F (70 degrees C), about 15 minutes more.
Remove from the oven, and allow to rest for 5 minutes before removing toothpicks and slicing.
Notes:
we use pork tenderloins instead... and the cooking time took longer than indicated in the recipe above (could also be because I wrapped the pork in about 3 time the amount of bacon called for)... but in the end... this was yummy.
