For the broth, place the garlic, cream, coriander and chilli flakes into a small food processor and blend until smooth.
Pour the mixture into a large frying pan or wok and bring to the boil. Add the carrot batons and cook for 4-5 minutes, or until just tender.
Heat the vegetable oil in a separate frying pan, add the pak choi and fry for 1-2 minutes on each side. Place the pak choi pieces into two serving bowls and pour over the broth.
Meanwhile, for the crisp fried noodles, place the vegetable oil into a deep, heavy-bottomed saucepan and heat until a small cube of bread sizzles and turns golden when dropped into it. (CAUTION: hot oil can be dangerous. Do not leave unattended.)
Place the blanched noodles into the hot oil and fry for 1-2 minutes, or until crisp. Remove with a slotted spoon and drain on kitchen paper.
To serve, place the crisp noodles on top of the broth in each bowl and garnish with coriander.
