2 red chillies, sliced (leave the seeds in if you like it hot)
Pour the stock into a large pan, add the ginger and spices, then leave to simmer and infuse for 10 mins. Soak the noodles according to the pack instructions, then drain and rinse.
Add the fish sauce and lime juice to the stock and taste for seasoning - add more fish sauce if you like. Divide the noodles between four bowls, then top with the shredded meat, beansprouts and a scattering of herbs, spring onion and chillies. Ladle the hot stock over the noodles, then serve with more herbs and lime wedges for squeezing.
