Ingredients

• Napa Cabbage: (1 large head, about 4-5 lbs) This is the star! Look for a firm, heavy head with crisp, green outer leaves. Avoid any with brown spots or wilting.
• Kosher Salt: (1/2 cup + 2 tbsp, or as needed) Crucial for drawing out water and starting the fermentation. Use coarse kosher salt; its larger grain size allows for better control during salting. Avoid iodized salt, as iodine can interfere with fermentation.
• Korean Radish (or Daikon): (1 cup, julienned) Adds a crisp texture and a subtle peppery sweetness that balances the spice.
• Carrot: (1/2 cup, julienned) For color, a touch of sweetness, and another layer of texture.
• Scallions: (6-8 stalks, cut into 2-inch pieces) Provides a fresh, oniony bite.
• Garlic: (1 head, about 10-12 cloves, minced) Essential for that pungent, aromatic depth characteristic of kimchi.
• Ginger: (1-inch piece, grated) Adds a warm, spicy kick and aids in fermentation.
• Onion: (1/2 small, grated or pureed) Contributes sweetness and a foundational flavor to the seasoning paste.
• Gochugaru (Korean Chili Flakes): (1/2 cup, or to taste) This is where the signature red color and heat come from. Look for flakes (coarse powder) rather than fine powder for better texture and less muddiness. Adjust to your preferred spice level.
• Fish Sauce: (1/4 cup) Provides umami depth and a salty kick. Traditional and highly recommended for authentic flavor.
• Fermented Salted Shrimp (Saeujeot): (1 tbsp, optional but traditional) A small amount adds incredible depth and a unique savory complexity. If using, mince it finely.
• Sweet Rice Flour (Glutinous Rice Flour): (2 tbsp) Used to make a thin porridge that acts as a binder for the seasoning paste, helping it cling to the cabbage leaves.
• Sugar: (2 tbsp) Feeds the good bacteria for fermentation and balances the salty, spicy, and sour flavors.
• Optional Add-ins (brief):
• Buchu (Asian Chives): (1/2 cup, cut into 2-inch pieces) Adds a mild garlicky-onion flavor.
• Minari (Korean Watercress): (1/2 cup, cut into 2-inch pieces) Offers a unique, slightly bitter, herbaceous note.

Directions

1. Step A — Prep and Salt the Cabbage
2. Prepare the Cabbage: Remove any bruised or damaged outer leaves from the napa cabbage. Trim the very bottom of the core, but leave enough intact to hold the leaves together.
3. Split the Cabbage: Carefully split the cabbage head lengthwise into quarters. To do this without shredding, make a small incision at the core with a knife, then use your hands to tear it the rest of the way. This preserves the leaf structure.
4. Salt the Cabbage: Rinse the cabbage quarters briefly under cold water. This helps the salt stick. In a large, clean bowl or food-safe tub, sprinkle a generous amount of kosher salt between each leaf, especially concentrating it on the thicker white parts. Don't be shy; this is crucial for drawing out water. Use about 1/2 cup of salt for a 4-5 lb cabbage.
5. Rest and Turn: Let the cabbage sit at room temperature for 1.5 to 2 hours. Every 30 minutes, turn and flip the cabbage quarters to ensure even salting. You'll notice the cabbage softening and releasing water.
6. Checkpoint: The Bend Test: After 1.5-2 hours, the cabbage leaves should be pliable and bend easily without breaking. If they snap, they need more time. Taste a small piece of the thick white part – it should taste pleasantly salty, like seawater, but not overwhelmingly so.
7. Rinse and Drain: Thoroughly rinse each cabbage quarter under cold running water 3-4 times to remove excess salt. Make sure to rinse between all the leaves. Gently squeeze out as much water as you can without tearing the leaves. Place them in a colander, cut-side down, and let them drain for at least 30 minutes to an hour.
8. Step B — Make the Sweet Rice Porridge
9. Cook the Porridge: In a small saucepan, whisk together 2 tablespoons of sweet rice flour with 1 cup of cold water until smooth. Place over medium heat and cook, stirring constantly, until the mixture thickens into a translucent, glue-like porridge. This usually takes about 5-7 minutes.
10. Checkpoint: Thickness: The porridge should be thick enough to coat the back of a spoon, but still pourable. Avoid lumps.
11. Cool Completely: Transfer the porridge to a bowl and let it cool completely to room temperature. This is important before mixing it with other ingredients to prevent cooking the aromatics.
12. Step C — Make the Seasoning Paste (Kimchi Paste)
13. Combine Aromatics: In your large mixing bowl, combine the cooled sweet rice porridge, minced garlic, grated ginger, grated onion, fish sauce, and finely minced fermented salted shrimp (if using).
14. Add Gochugaru: Stir in the gochugaru and sugar. Mix well until everything is evenly combined.
15. Add Vegetables: Fold in the julienned Korean radish, carrot, and cut scallions (and optional buchu/minari, if using).
16. Checkpoint: Paste Consistency and Aroma: The paste should be a vibrant red, thick enough to cling to the vegetables, and smell wonderfully aromatic – a mix of spicy, savory, and slightly sweet. Adjust gochugaru or sugar to your preference.
17. Step D — Season the Cabbage and Pack
18. Season the Cabbage: Put on food-safe gloves! This paste will stain your hands and can cause irritation. Take one cabbage quarter at a time. Carefully spread the seasoning paste between each leaf, from the base of the leaf up to the green tip. Be thorough, but don't over-apply.
19. Fold into Packets: Once each leaf is coated, gently fold the cabbage quarter in half or roll it into a neat packet. This helps keep the leaves submerged in brine later.
20. Pack Tightly: Place the seasoned cabbage packets tightly into your clean 2-quart jar or container. Press down firmly to remove any air pockets and encourage brine to form.
21. Checkpoint: Brine Appearance: Within an hour or two, you should start seeing liquid (brine) rising in the container as the salt continues to draw water from the cabbage.
22. Headspace Guidance: Leave about 1-2 inches of headspace at the top of your container. This is crucial because the kimchi will expand and produce gas during fermentation. If you have any leftover paste, you can spread it over the top of the packed kimchi. If you have extra brine, pour it over the kimchi. Ensure the kimchi is submerged under its own brine as much as possible.
