Combine the gochujang, honey, soy sauce, sesame oil, garlic and ginger in a bowl. Pierce the pork loin several times with a sharp paring knife and then place it in a FoodSaver® Bag. Pour the marinade on top and massage the marinade into the pork to coat it well. Vacuum seal the bag using the FoodSaver® vacuum sealer to remove all the air. This will ensure that the food will sink in the water bath and be completely submerged.
