Preheat oven to 500 F. Place the cedar plank in a large roasting pan with the apple juice, cinnamon sticks, nutmeg, cloves and cardamom pods. (Reserve 2 tablespoons of apple juice for basting). With a sharp knife, score the pork loin about 1/2 deep and rub the garlic, salt and pepper into the loin. Place the loin on the plank and sear for 15 minutes. Now reduce the oven temperature to 375 F and roast for 1 hour. Meanwhile mix tarragon, maple syrup, apple juice (reserved) and mustard in a small bowl and start basting at the one hour mark and again every 15 minutes until the internal temperature reaches 145-150º. Remove from oven and baste once more. Let pork loin rest for another 10 minutes before cutting into 5 thick chops. Meat will be slightly pink.

 

Serve with remaining sauce, and your favorite side dish.
