Dumplings, also known as "doughboys", or Maori bread usually accompany the meal to soak up the soupy goodness. |  | Ingredients |  | A bunch of puha (watercress) 1 pork tenderloin 1 kumara (sweet potato,) peeled and diced 1/2 white onion 6 baby tomatoes 3 spring onions, thinly sliced 1 litre of chicken stock 2 cups of water 1 tsp of sea salt Pre-made pumpkin dumplings 1/2 kg of pork bones |  | Instructions |  | 1 Add the chicken stock, 2 cups of water and pork bones to a large stock pot. Bring to the boil and simmer for 1 hour.
2 Soak the watercress in cold water for about 10 minutes and then wring it out to get rid of the bitter juices. Set aside.
3 Add the kumara, 1/2 white onion, tomatoes and spring onions to the soup stock. Simmer for 15 minutes.
4 Cut the pork filet into 1 inch slices and add to the stock. Add salt and lower heat and cover pot. Simmer gently for 15 minutes.
