Pork Miso Soup (豚汁 / Tonjiru) is my all-time favorite soup with Tonkatsu.

Make sure to use a blend of both White Miso (Shiro) and Red Miso (Aka). The combination of both is together is phenomenal in this soup.

If you can't make dashi, I recommend buying dashi packets over using the dashi granules.

Ingredients (14)

Dashi Stock

Pork Miso Soup (Tonjiru)

Instructions

Dashi Stock

  1. If you don't want to make dashi, use dashi packets or granules and skip this entirely.

  2. Steep Kombu (45 g) in Filtered Water (1 ½ liters) in a stockpot at 60 °C for about 30min

  3. Strain, and bring temperature to about 80 °C

  4. Add Katsuobushi (40 g) to the dashi, and allow to steep for 30sec to a few min

    this is preference, I would go closer to 3 minutes to let the katsuobushi steep longer. taste as it steeps

Prep-Konyakku

  1. Konyakku, or Konjac, needs to be prepped in order to remove it's fishy odors. Prepare a small pot of boiling water and grab any salt.

  2. After cutting the konyakku into manageable match sticks, season with salt and mix thoroughly. This will draw out some initial odors

  3. Blanch the konyakku in boiling water for 3 min

  4. Shock in cool water, then reserve until ready to use

Pork Miso Soup (豚汁 / Tonjiru)

  1. In a sauce pan, heat up the sesame oil (1 Tbsp) over medium heat

  2. Add sliced pork (100 g) and sauté until no pink / raw meat is visible

  3. Add onions (30 g) and sauté until lightly translucent, maybe 1 to 2 minutes

  4. Add the remaining burdock (20 g), daikon (50 g), carrot (30 g), konyakku (60 g). Sauté for a few minutes until fragrant

  5. Add dashi (750 mL) and scrape the bottom of the pan to remove any fond. While the heat is on medium, make sure to skim any foam and cook vegetables until tender (about 10 to 15min)

  6. It is very important to not expose miso to boiling temperatures, or else the aromas and flavors will disappear.

  7. Lower the heat to med-low, and dissolve the white miso (40 g) and red miso (30 g) into a strainer to disperse into the soup. Alternatively, ladle a small portion of miso in a separate bowl, whisk until miso is dispersed, then pour back into soup.

    When reheating this soup, I suggest reheating on med-low heat, don't try to boil the miso

  8. Adjust miso to taste, then garnish with sliced green onion rounds.
