Steps

1. In a bowl, combine Soy Sauce 4 tbsp, Cooking Sake (Rice Wine) 3 tbsp, Mirin (Sweet Rice Wine) 4 tbsp, Hondashi (Dashi Granules) 1 tbsp, and Sugar 4 tbsp. Mix well to create the simmering liquid.
   🕒 00:16
2. Cut Onion 1/2 in half lengthwise, then slice into 5mm thick pieces.
   🕒 00:43
3. Tear Maitake mushrooms 1 pack into bite-sized pieces by hand. (Pro Tip: Maitake mushrooms have natural lines; tearing them along these lines will create nicely sized pieces.)
   🕒 00:56
4. Trim the root end of Leek 1 stalk and cut into 5cm pieces. (Pro Tip: The green parts also help remove any gamey smell from the beef, so wash them lightly and use.)
   🕒 01:09
5. Boil Shirataki noodles 200g in hot water for about 2 minutes to remove any bitterness. Cut into bite-sized pieces with kitchen scissors. (Pro Tip: Boiling in hot water thoroughly removes the unpleasant odor.)
   🕒 01:30
6. Thoroughly pat dry the surface of Seared tofu 1 block with paper towels. (Pro Tip: Wiping off the moisture prevents the simmering liquid from becoming diluted, allowing the flavors to penetrate better.)
   🕒 01:50
7. Cut the Seared tofu in half horizontally, then cut each half into approximately 6 bite-sized pieces. (Pro Tip: If the pieces are too large, they won't absorb the flavors well, so be mindful of the size.)
   🕒 02:07
8. Heat a frying pan over high heat without oil, then add the Leeks and grill until browned on both sides.
   🕒 02:33
9. Remove the nicely browned Leeks from the pan.
   🕒 02:51
10. Lightly oil the same frying pan and heat over medium heat. Add Beef belly 200g and stir-fry thoroughly.
    🕒 03:00
11. Sprinkle Salt a pinch over the stir-frying Beef to season.
    🕒 03:11
12. Remove the Beef once it's cooked through.
    🕒 03:24
13. Add the prepared simmering liquid to the frying pan, utilizing the beef drippings. Arrange the Onions, Maitake mushrooms, Seared tofu, and the grilled Leeks neatly in the pan.
    🕒 03:30
14. Bring the simmering liquid to a boil over medium heat.
    🕒 04:00
15. Once the ingredients are cooked and softened, create a space in the pan and add the boiled and cut Shirataki noodles.
    🕒 04:09
16. After adding all the Shirataki noodles, cover with aluminum foil as a lid. Reduce heat to low and simmer for 20 minutes.
    🕒 04:29
17. After 20 minutes, remove the lid and create a space to add the Beef. If any ingredients are not submerged in the simmering liquid, flip them over to ensure they are coated.
    🕒 04:36
18. Add the stir-fried Beef to the empty space. Increase heat to medium and simmer gently for about 2 minutes.
    🕒 04:50
19. Serve in bowls and enjoy!
