Prepare the marinade. Mix all the dry ingredients in a container. Mix the garlic and onion with the other marinade ingredients. Add white wine vinegar and stir. Boil water and pour boiling water over the herbs and spices. Place the knuckle in the marinade and turn the meat over until it is completely covered with the mixture. Leave the knuckle to marinate in the refrigerator for at least an hour.
Make the sauce. Mix honey and mustard in a bowl, taste and add salt to taste.
Bake the meat. Mix the garlic cloves with salt. Remove the knuckle from the marinade, make deep cuts on the meat with a knife about 4-5 cm apart and insert the garlic plates there. Wrap the knuckle in foil, leaving no gaps, and place in an oven preheated to 250 degrees. Bake the pork knuckle for 1 hour.
Finish cooking. Remove the pork knuckle from the oven, unwrap the foil and bake for another 30 minutes until the crust is thick and golden brown.
