Garlic Gochujang Mixture:



  • Prepare Ingredients:
    Napa Cabbages - Cut napa cabbages into 3 to 4 pieces.
    Green Onions - Separate the white parts from the green onions. We're pressure cooking the white part with the pork bones, and using the green part as a garnish.
    Potatoes - Depending on the size of your potatoes, cut them in halves or quarters. Place the potato chunks under cold water to prevent them from browning.

  • Optional Step - Clean Pork Bones: Bring 6 cups (1.5L) of cold water to a boil. Boil the pork bones for 3 - 5 minutes to clean and remove the excess fat. Remove the pork bones, then rinse them under cold water.
    *Note: This cleaning step will yield a clearer soup and you won't have to skim the scum at the end.

  • Pressure Cook Pork Bone Soup: In a clean Instant Pot inner pot, add 6 crushed garlic cloves, 3 (5g) ginger slices, quartered onion, the white part of green onions, 1 tbsp (15ml) regular soy sauce, 2 tbsp (30ml) fish sauce, 2 bay leaves, and 2 tbsp (32g) fermented soybean paste. Add 3lb - 3¼lb pork neck bones and 7 cups (1.75L) cold water in the Instant Pot.
    Close lid, then turn Venting Knob to Sealing position. Pressure Cook at High Pressure for 22 minutes + Natural Release for 15 minutes. Open the lid carefully.
    When Instant Pot is releasing pressure, mix together 2 tbsp (30g) gochujang, ¼ tsp (0.5g) ground black pepper, 6 minced garlic cloves, and optional - 2 tbsp (16g) ground perilla seed or perilla powder.

  • Boil Pork Bone Soup: Bring the pork bone soup to a full boil with the “Saute More or High” function. Add the garlic gochujang mixture in Instant Pot, then mix well. Let the pork bone soup boil for 4 - 5 minutes.

  • Add Potatoes and Cabbages: Add in potato chunks, then layer the napa cabbages on top.
    *Pro Tip: Set aside some of the pork bones to prevent the soup from boiling over.
    Let the soup boil until the potato chunks are fully cooked (~8 - 15 mins) depending on the size of the potato chunks.
    *Pro Tip: Due to the nature of pressure cooking, the soup will be quite thin initially. So, it’s very important to boil the soup for an extra 15 – 20 mins to add body to the soup.

  • Season Gamjatang: When the potatoes are about 3 minutes away from being fully cooked, taste-test the soup. If you're using bean sprouts, add them here. Taste and adjust the seasoning with more salt, soy sauce, fish sauce, and Korean fermented soybean paste if necessary.
    *Note: Make sure you don't overseason by adding the seasonings gradually as you continue to taste & adjust.
