Korean Kimchi (Traditional Fermented Wombok)

Prepare the wombok: Remove any damaged outer leaves. Cut wombok lengthwise into quarters, leaving the core partially attached to hold leaves together. If using half wombok, cut into halves. Rinse thoroughly under cold running water, separating leaves slightly to remove any dirt between layers. Shake off excess water.

Salt the cabbage (critical step): Dissolve ½ cup coarse salt in 6 cups water to create brine. Place wombok quarters in a large bowl and pour brine over, ensuring all pieces are submerged. Sprinkle additional salt between the leaves, especially on the thick white parts—these need more salt to draw out moisture. Place a plate on top to keep cabbage submerged. Let sit at room temperature for 6-8 hours or overnight, turning pieces every few hours for even salting.

Test the salt cure: After 6-8 hours, the cabbage should be significantly wilted and flexible—the thick white parts should bend easily without snapping. Taste a piece of the thick rib—it should be pleasantly salty but not inedibly so. If still too crunchy or not salty enough, continue brining for another hour or two.

Rinse thoroughly: Drain salted cabbage and rinse under cold running water 3 times, gently squeezing to remove excess salt while being careful not to tear the delicate leaves. The final rinse water should taste only slightly salty. Drain in a colander for 1 hour, occasionally pressing gently to remove water. The cabbage should be limp but not dripping wet.

Make the rice flour paste: This creates a smooth, thick base that helps the seasoning adhere and provides sugars for fermentation. Mix glutinous rice flour with ½ cup water in a small saucepan. Cook over medium heat, stirring constantly, until it thickens to a translucent paste similar to thin porridge, about 3-4 minutes. Let cool completely—using hot paste will kill beneficial fermentation bacteria.

Create the kimchi paste: In a large bowl, combine cooled rice flour paste, gochugaru, fish sauce, shrimp paste if using, sugar, minced garlic, and minced ginger. Mix thoroughly into a thick, vibrant red paste. The consistency should be similar to thick barbecue sauce. Taste carefully (it’s spicy!)—it should be salty, spicy, funky, and slightly sweet. Add julienned radish, carrots, and spring onions to the paste, mixing to coat them thoroughly.

Coat the cabbage: Wearing food-safe gloves (gochugaru stains and burns), take each cabbage quarter and separate the leaves slightly. Using your hands, spread kimchi paste generously between every leaf, starting from the outer leaves and working inward. Be thorough—every surface should be coated. Pay special attention to thick white ribs which need more paste. The work is messy but meditative.

Pack for fermentation: Pack kimchi tightly into clean glass jars or an airtight container, pressing down firmly to remove air pockets. The cabbage should be submerged in its own juices—if not, make extra brine (1 tbsp salt dissolved in 1 cup water) and add enough to cover. Leave at least 2-3cm headspace as fermentation produces gas and liquid that can overflow.

Ferment at room temperature: Seal containers loosely (to allow gas to escape) and leave at room temperature (18-22°C) for 2-5 days. Check daily—you should see small bubbles forming and liquid increasing. Press down cabbage if it rises above liquid. Taste after 2 days—it should be tangy, slightly fizzy, still crunchy. Ferment longer for more sour, funky flavor. Warmer temperatures speed fermentation; cooler temperatures slow it.

Refrigerate and age: Once kimchi reaches desired tanginess (beginners often prefer 2-3 days for milder taste), seal tightly and refrigerate. It’s ready to eat immediately but continues developing flavor. Peak flavor occurs after 2-3 weeks in the fridge. Properly stored, kimchi keeps for several months, becoming increasingly sour and soft over time.
