Chop all the herbs and mix well with salt, pepper, and crushed garlic. Rub this mixture into the pork loin and leave to rest for about an hour. Before baking, sprinkle with chestnut honey, coating it completely. Place in a preheated oven at 190°C for 20 minutes, then lower the temperature to 160°C and continue cooking for 40 minutes. Remove from the oven and let it rest for about 15 minutes before serving the meat sliced. Use the juices from the roast to mix with a few teaspoons of mustard and honey, creating a delicious sauce to decorate and flavor the meat.
