METHOD
-
spices
In a mortar, mix and crush all the ingredients for the spice blend.
-
meat
Place the meat in a bowl and rub it thoroughly with the spices. Cover with plastic wrap and refrigerate for 6–24 hours.
-
meat
When the meat is ready for roasting, prick the skin evenly to help it crisp up. Insert two metal skewers crosswise through the meat so it can rest over a deep roasting pan with vegetables, keeping the skin stretched and taut.
-
roast
Place the roughly chopped vegetables into a large, deep roasting pan and pour in the stock. Set the meat over the pan so it sits above the vegetables, using the metal skewers to support it. Preheat the oven to 170°C (340°F) and position the rack one level below the center. Roast the meat first for 40 minutes at 170°C (340°F), then reduce the temperature to 120°C (250°F) and continue roasting for about 4 hours and 30 minutes, or until the internal temperature reaches 85–90°C (185–195°F), checking with a meat thermometer. Baste the meat with dark beer every hour.
-
roast
Remove the meat from the oven and brush it with wine vinegar. Move the oven rack to the center position and roast the meat for another 25–30 minutes at 230°C (445°F), until the skin is crispy. Keep a close eye on it during the final 15 minutes of roasting, as the pork knuckle can brown too quickly.
-
sauce
Strain the vegetables and sauce through a fine sieve into a saucepan. Place over medium heat and cook for 10 minutes, until about two-thirds of the liquid has evaporated.
-
serve
Slice the pork knuckle and serve it with your chosen side dishes, for example, braised sauerkraut, potatoes, and the sauce.
