Step 1

Place steak, spice and cornflour in a bowl and toss well. Soak noodles in a bowl of boiling water for 2 minutes, drain well, then set aside. Place a wok over high heat and add half the peanut oil. When it's smoking, add steak and stir-fry quickly for 1 minute. Remove.

Step 2

Add remaining oil, then stir-fry the lemongrass, garlic, ginger, shallots, leek and carrot for 1 minute. Add tamari, rice wine, stock, noodles and beef. Keep tossing together over high heat for a further 1-2 minutes or until cooked through and well combined.
