For an Authentic stir-fry Robert advises -

• Make sure your wok is clean and hot before cooking
• Prepare ahead, e.g. peel, cut, etc
• Use fresh vegetables and meat, and slice small
• Hot wok, hot oil, and start cooking! The quicker the cooking the better
• Use fresh garlic and ginger, light and dark soy sauce & 5-spice.
• Always use rice wine and sesame oil
• Tip for fried rice - use cold cooked rice
