• It's easier to cut the pork belly if it's slightly frozen, so put it in the freezer for 15 minutes before you cut it. Meanwhile, gather all the ingredients.
  

To Prepare the Ingredients

• Take out the pork from the freezer and cut it into 1-inch (2.5 cm) pieces.
  
• Scrape the gobo skin with the back of your knife. The flavor of the gobo is right underneath the skin; therefore, you only need to scrape off the outer skin. Do not use a peeler.
  
• Make a cross incision on the end of the gobo about 1 inch (2.5 cm) deep. This helps make shaving the gobo easier. Rotate the root as you shave the end of the gobo, like how you would sharpen a pencil with a knife. Soak the shaved gobo in water to prevent discoloration.
  
• Discard the dirty water and rinse the gobo under running water.
  
• Cut off both ends of the taro and peel the sides with the knife (or peeler).
  
• Cut the taro into ⅓-inch (8 mm) slices and soak them in water to remove the sliminess.
  
• Cut the onion in half lengthwise and cut it into thin slices.
  
• Peel the daikon and cut it in half lengthwise.
  
• Cut the daikon halves in half lengthwise again (now they are quartered) and cut into ⅛-inch (3 mm) slices. If your daikon is skinny, cut it into thin half-moon-shaped slices.
  
• Peel and cut the carrot in half lengthwise, and then slice thinly.
  
• Cut the konnyaku into small and thin rectangular pieces.
  
• Sprinkle the salt on the konnyaku and rub it well with your hands. Let it stand for 5 minutes. Tip: The salt releases moisture along with the unwanted odor from the konnyaku.
  
• In the meantime, bring a small saucepan of water to a boil. Once boiling, add the konnyaku.
  
• Cook the konnyaku for 2-3 minutes, drain the water, and set aside. Tip: This helps to remove the unwanted odor.
  
• Slice the negi (long green onion) diagonally.
  
• Remove the excess oil from the aburaage with a piece of paper towel.
  
• Cut the aburaage in half lengthwise and thinly slice it.
  
• Peel and grate the ginger and measure the amount you need (1 tsp for 8 servings).
  
• Cut the green onions into thin small rounds to use as garnish on top of the miso soup. Keep them in a bowl.
  

To Cook the Tonjiru

• Preheat a large pot (I use this Le Creuset Dutch oven) over medium heat. When hot, add the sesame oil.
  
• Add the pork belly and stir-fry with a spatula.
  
• When the pork is no longer pink, add the onion.
  
• Stir-fry the onions. Then, add the daikon and carrot slices.
  
• When the ingredients are coated with oil, add the gobo and taro.
  
• Add the konnyaku, aburaage, negi, and dashi. There should be just enough dashi to cover the ingredients. If not, add more dashi or water.
  
• Stir to mix, cover with a lid, and bring it to boil.
  
• When boiling, lower the heat and skim off the scum and fat from the soup.
  
• Simmer, covered with the lid, until the root vegetables are tender, about 10-15 minutes.
  
• The Tonjiru is done cooking when a skewer inserted into a tough and thick vegetable pierces through. Turn off the heat. If you are preparing this dish ahead, stop here and let it cool completely before storing the pot in the refrigerator.
  

To Serve

• For the best flavor and aroma, add the miso right before serving, if possible. Add the miso using a strainer. (Tip: Always start adding a little less than the recipe calls for; each brand/type of miso has different saltiness.) If you don’t have a strainer, let the miso completely dissolve in the ladle first before releasing it to the soup. Taste the soup. If it's too salty, add dashi or water to dilute.
  
• If the soup needs more seasoning, add more miso (I added 1 Tbsp for 8 servings). When you are done adding the miso, add the grated ginger. Tip: When you add the tofu (always add tofu after the miso as it is delicate), make sure your miso soup has a slightly stronger taste because the moisture from the tofu will dilute the flavor.
  
• Tear the tofu into small pieces and add them. Alternatively, you can cut the tofu into cubes instead of tearing it. Tip: Tearing adds more surface area to the tofu and will help it absorb more miso flavor from the soup.
  
• When you are ready to serve, reheat the miso soup on medium-low heat and keep it at a low simmer. NEVER let the miso soup boil because miso will lose its flavor.
  
• Serve the Tonjiru in miso soup bowls, sprinkle with green onion, and serve immediately.
  

To Store

• Let the Tonjiru cool completely before storing it in the refrigerator. Consume within 5 days.
