Thai-style drunken noodles with prawns

Place the noodles in a large heatproof bowl, cover with just-boiled water and soak for 6 minutes. Drain and rinse off the excess starch under the cold tap, then set aside. Meanwhile, in a small bowl, mix the soy, fish and oyster sauces with the sugar and 1 tbsp water.

Put 1 tbsp oil in a wok or large frying pan over a high heat. Once very hot, add the prawns. Fry for 5 minutes until cooked through, pink and opaque; tip on to a plate and set aside.

Heat the remaining 1 tbsp oil and stir-fry the onion and asparagus for 1 minute. Add the garlic and ginger, then fry for another minute. Tip in the chilli and most of the basil; fry for 30 seconds, then add the noodles and soy sauce mixture and fry for 1 more minute. Toss the prawns through the noodles and heat for a final 1 minute. Scatter with the remaining basil leaves, and serve with lime wedges for squeezing over.
