Prepare the Cabbage – Wash and slice the Napa cabbage. Place it in a large bowl and set aside.
Make the Seasoning Paste – In a small saucepan, mix glutinous rice flour and water over low heat, stirring constantly until thickened. Let cool.
Combine the Ingredients – In a bowl, mix gochugaru, grated ginger, garlic, fish sauce, and brown sugar. Stir in the cooled rice paste to create a thick seasoning sauce.
Mix Everything Together – Add the sliced carrots and the seasoning paste to the Napa cabbage. Toss until evenly coated.
Let It Rest – Allow the cabbage to sit for at least 30 minutes before serving to let the flavors develop.
Serve and Enjoy – Eat fresh or store in an airtight container in the refrigerator for up to 3 days for even deeper flavor.
