Place the chicken carcass into a large saucepan and pour over enough boiling water to almost completely cover it. Bring to a vigorous simmer and simmer for 30 mins then bring to a gentle simmer and leave with a lid on for 3-4 hours so the broth is super flavourful and the bones are clean. Once done, remove all the bones and debris until only the chicken stock remains.

Carefully pour the stock into a large jug or container and leave in the fridge over night until set into a jelly. The next day there will now be a layer of white resedue on the top, remove this so only the light golden opaque jelly remains. Return the solidified stock to a large saucepan over a medium low heat and allow to melt back into a liquid.

Add the soy sauce, white pepper, sugar, tamarind sauce, ginger, garlic, fish sauce, chilli flakes and oyster sauce. Stir and bring to a gentle simmer. Add in the vegetables and the roast chicken pieces plus the noodles. Simmer until the noodles have loosened apart and the vegetables are tender. Do not overcook them, you still want a good bite to them.
