                Thoroughly rinse pork hocks under cold water, then pat dry. In a large pan over high heat, sear the hocks on all sides until the skin is evenly browned to develop flavor and enhance crispness in the final roast.

                Transfer the seared hocks to a large stockpot. Add carrots, parsnips, celery root, onion, bay leaves, allspice berries, peppercorns, and 1 teaspoon salt. Cover with water so hocks are fully submerged. Bring to a boil, reduce heat, and simmer gently for 2 hours until the meat is tender. Reserve 240 ml of the cooking liquid for roasting.

                Pour reserved cooking liquid and any remaining marinade around the hocks in the roasting pan. Cover with foil and roast in the preheated oven for 1 hour. Remove foil and continue roasting for 20 minutes more, basting occasionally, until the skin is crisp and golden brown.
