Speedy prawn noodle soup

Method

1. Bring a medium saucepan of water to the boil, then gently lower in the eggs and cook for 6 minutes for soft-boiled. Drain and run under cold water to stop them cooking more. Carefully peel, then cut in half and set aside. Meanwhile, soak the dried shiitake mushrooms in 100ml boiling water for 5 minutes.
2. Put the stock, tamari sauce and five-spice in a large pan. Drain the mushrooms through a fine sieve into the pan, then add the mushrooms (discard any grit in the sieve). Bring to the boil, then reduce the heat and simmer for 2 minutes. Add the prawns and simmer for a further 3 minutes until pink and cooked through.
3. Season the stock to taste with freshly ground black pepper or more tamari sauce, if you like.
4. Cook the noodles according to the packet instructions, then drain and divide among 4 bowls. Pour over the stock and top each bowl with 2 egg halves, some sliced spring onions and the sweetcorn and chopped coriander.
