Mastering Authentic Baechu Kimchi: Sister’s Secret to Perfectly Fermented Napa Cabbage

Instructions

• Prepare the Napa Cabbage: On your **Natural end-grain acacia wood cutting board**, carefully remove any outer, damaged leaves from the 3 large heads of napa cabbage and set them aside. Make a cross-cut (X-shaped incision) halfway through the bottom core of each cabbage. Using your hands, gently tear the cabbage in half vertically, allowing the leaves to separate naturally. This prevents excessive breakage compared to cutting all the way through. Further cut any very large halves into quarters, adjusting size as needed for even brining.
  
• Brine the Cabbage: In a large brining container or tub, dissolve 2 cups (480g) of coarse sea salt into 1 liter (4.2 cups) of water. Immerse the prepared cabbage pieces into this salt water, ensuring they are thoroughly soaked. Take the remaining 1 cup (240g) of coarse sea salt and sprinkle it evenly between the layers of each cabbage piece, focusing on the thicker white parts. Press the cabbage down firmly and place a heavy plate or bowl filled with water on top to submerge them, helping them brine faster. Allow the cabbage to brine for 3 hours, flipping them twice during this time to ensure even salting. (General rule: 1 cup of salt per large cabbage head).
  
• Cook the Flour Paste (Puri): In a large stockpot, whisk together 600ml (2.5 cups) of water and 6 tablespoons (50g) of all-purpose flour until smooth. Heat the mixture over medium-low heat, stirring continuously with a wooden spatula, until it thickens into a smooth, translucent paste. This usually takes about 5-7 minutes. Once thickened, remove from heat and let it cool completely. (You can also use sweet rice flour for a chewier texture).
  
• Rinse and Drain the Brined Cabbage: After 3 hours of brining, the cabbage should be flexible and slightly translucent. Thoroughly rinse the cabbage under cold running water 5 times to remove excess salt. Be gentle to avoid damaging the leaves. Place the rinsed cabbage in a large colander and let it drain for at least 30 minutes to an hour, allowing as much water as possible to drip out. Gently squeeze out any remaining water without tearing the leaves.
  
• Prepare the Kimchi Paste Aromatics: While the cabbage drains, prepare the aromatic base for the kimchi paste. In a blender or food processor, combine the chopped fresh red chili peppers (200g), peeled garlic (200g), peeled ginger (40g), and roughly chopped onion (350g). Blend until a smooth, thick paste forms. Set aside.
  
• Assemble the Kimchi Seasoning: In your designated **Extra-Large Stainless Steel Mixing Bowl**, combine the cooled flour paste from Step 3, the blended aromatic paste from Step 5, and the prepped green onions (200g, cut into 5cm pieces). Add 3 cups (360g) of Korean chili flakes (gochugaru), 1/2 cup (120ml) of Korean anchovy sauce, 1/2 cup (120ml) of Korean green plum extract, 1/2 cup (120g) of fermented shrimp paste, 1/2 cup (60g) of chili seeds, and 2 tablespoons of sugar. Mix all ingredients thoroughly with a large spoon or your gloved hands until a uniformly vibrant red paste forms. Allow the paste to rest for 15-20 minutes to let the gochugaru bloom and deepen in color.
  
• Coat the Cabbage and Finish: Wearing rubber gloves, take each drained cabbage piece and generously spread the kimchi seasoning paste between every leaf, ensuring full coverage from the white core to the green tips. Once each piece is thoroughly coated, gently fold the cabbage in half or roll it up and place it snugly into airtight fermentation containers. Do not pack too tightly, leave a little room for fermentation gases. Store at room temperature for 1-2 days to begin fermentation, then transfer to the refrigerator for longer storage and continued slow fermentation. Enjoy your authentic homemade Baechu Kimchi!
