Cook the noodles to packet instructions, drain and toss them through with some toasted sesame oil and place in four bowls.
Heat a wok over high heat and add 2 tbsp of vegetable oil. Add the garlic and ginger and stir for a few seconds before quickly adding the minced beef and chilli. As the beef starts to turn brown, add the rice wine. Then stir in the baby gherkins, cook for about 4 minutes until fragrant, and season with some light soy sauce.
In a small wok or pan, heat 2 tbsp vegetable oil and stir fry the spring onions, sesame paste, chilli oil and vinegar. Add the chicken stock and bring to the boil.
Into each bowl ladle the sauce stock, then the meat, followed by the coriander. Drizzle some chilli oil and toasted sesame oil (to taste) around the edges of the dish in the soup stock, and serve immediately.
