Recipe 🍳
- Prepare store-bought galbi by cutting it into large pieces or tearing it apart by hand to preserve its chewy texture.
- Cut 1 onion, 1 zucchini, and 1 potato into 1–2 cm cubes.
- Heat 2 tablespoons of perilla oil in a pot, then add the prepared galbi along with the diced onion, zucchini, and potato.
- Add 500g of doenjang, 100g of gochujang, 2 tablespoons of minced garlic, half a tablespoon of sugar, and 1 cup of rice washing water. Stir well and bring to a boil.
- Once vegetables are about halfway cooked and starting to release moisture, add chopped green onion and green chili pepper and simmer together.
- Grate the remaining 1 potato and extract its juice. Add the juice to the boiling gangjungjang to thicken and adjust the consistency.
- For longer storage, add 1/3 cup of soju and simmer briefly to finish.

Cooking tips 💡
- Avoid overcooking the vegetables in the gangjungjang, as they may become mushy—cook just until they're half-done to maintain a crisp texture.
- Instead of using starch powder to prevent thinning, adding fresh potato juice enhances the depth of flavor and adds a rich, savory note.
- Adding 1/3 cup of soju at the end helps eliminate any off-flavors and provides a sterilizing effect, allowing the gangjungjang to be stored in the refrigerator for more than a week.
