Place all the Master Stock ingredients into a stock pot, bring to a boil, reduce and simmer for about 20 minutes. This allows the flavors to combine together.

While the stock is simmering, prepare the duck. Remove the neck and fatty tail. Place 1 tablespoon of oil in a wok or a pan. Sear the duck, like you would sear a piece of meat for a slow cooker. After a few minutes, turn the duck over. On parts of the duck that don't reach the pan, spoon some hot oil on them. The skin will crisp up slightly as the fat renders from the duck. Remove from heat.

Bring the Master Stock to a boil in a large stock pot. Place the seared duck into the stock. Most of the duck will be covered by liquid. If it's not fully covered, that's ok. Reduce to a simmer and cook the duck for 60 minutes. Flip the duck over every 15 minutes to ensure each side is evenly braised in the Master Stock. Preheat oven to 400°F/200°C.

Carefully remove the duck from the stock. Ensure the hot liquid is out of the duck cavity. Place on a roasting pan and roast in the preheated oven for about 15 minutes, until the skin is crispy. Don't let it burn, check at the 10 minute mark.

Serve with rice, steamed greens and Chinese Roasted Potatoes. Set aside some Master Stock to serve with the duck.
