Presoak rice noodles in hot water for about 5 minutes until aldente and drain and rinse with cold water and drain. Do not cook the rice noodles in the soup or otherwise they will soak up all the delicious broth. It is best to keep the rice noodles a little undercooked as they soften more when you ladle the hot soup over them upon the serving process. Set aside. (You can also use ramen noodles, udon, soba, mung bean noodles, sweet potato noodles, pasta noodles, etc..etc... just pre-cook them according to your directions and set aside. Use what you have in your pantry)
In a large bowl, combine sukiyaki beef (or just thinly sliced beef of choice), tamari or soya sauce, sesame oil, garlic, onion, ginger, dried red chili flakes, five spiced powder and salt and white pepper. Set aside while you prepare the vegetables.
Remove stems from mushrooms. If desired carve flower shape on top of mushrooms. See video for demonstration of this process. Peel and slice and quarter daikon radishes into ⅛ inch thick slices so they cook quicker.
Add olive oil (or oil of choice) to your large soup pot and add the marinated beef mixture. Stir fry until browned. Add beef broth, daikon radish slices and bring to a boil and then turn down to a medium simmer for about 15 minutes. Skim frequently with a spoon to remove the froth that forms on top of the soup pot. Season broth with salt and white pepper as desired.
Add mushrooms and bamboo shoots (or baby corn) simmer for about 5-8 minutes or until tender. Add green leafy vegetables of choice (we used spinach and Napa cabbage) and cook for 1-2 minutes. Adjust seasoning (add salt and white pepper to taste.)
Place pre-soaked aldente rice noodles into soup bowl. Scoop a large ladle of soup with beef, daikon radish, vegetables and loads of delicious broth into the soup bowl. Garnish with fresh chili's, if desired. Enjoy!
