While Kimchi may be an acquired taste for those not used to its pungent, fermented flavors, once converted you’ll enjoy it with everything from rice to omelettes to straight out of the jar. It can be endlessly alterable — try adding apples or rutabaga!
1 medium head Napa cabbage
1/4 cup non-iodine sea salt or kosher salt
1 tablespoon grated garlic (5 to 6 cloves)
1 teaspoon grated ginger
1 teaspoon sugar
2 to 3 tablespoons seafood flavor or water
1 to 5 tablespoons red pepper flakes or Korean red pepper powder (gochugaru)
8 ounces Korean radish or daikon, peeled and cut into matchsticks
4 scallions, trimmed and cut into 1-inch pieces (or onions)
4 carrots, trimmed and cut into matchsticks.
Cutting board and knife
Gloves (optional but highly recommended)
Plate and something to weigh the kimchi down, like a jar or can of beans
Clean 1-quart jar with canning lid or plastic lid
Bowl or plate to place under jar during fermentation
- Slice the cabbage: Cut the cabbage lengthwise into quarters and remove the cores. Cut each quarter crosswise into 2-inch-wide strips.
- Salt the cabbage: Place the cabbage and salt in a large bowl. Using your hands (gloves optional), massage the salt into the cabbage until it starts to soften a bit, then add water to cover the cabbage. Put a plate on top and weigh it down with something heavy, like a jar or can of beans. Let stand for 1 to 2 hours.
- Rinse and drain the cabbage: Rinse the cabbage under cold water 3 times and drain in a colander for 15 to 20 minutes. Rinse and dry the bowl you used for salting, and set it aside to use in step 5.
- Make the paste: Meanwhile, combine the garlic, ginger, sugar, and seafood flavor (or 3 tablespoons water) in a small bowl and mix to form a smooth paste. Mix in the red pepper powder, using 1 tablespoon for mild and up to 5 tablespoons for spicy.
- Combine the vegetables and paste: Gently squeeze any remaining water from the cabbage and return it to the bowl along with the radish, scallions, and seasoning paste.
- Mix thoroughly: Using your hands, gently work the paste into the vegetables until they are thoroughly coated. The gloves are optional here but highly recommended to protect your hands from stings, stains, and smells!
- Pack the kimchi into the jar: Pack the kimchi into the jar, pressing down on it until the brine rises to cover the vegetables. Leave at least 1 inch of headspace. Seal the jar with te lid.
- Let it ferment: Let the jar stand at room temperature for 1 to 5 days. You may see bubbles inside the jar and brine may seep out of the lid; place a bowl or plate under the jar to help catch any overflow.
- Check it daily and refrigerate when ready: Check the kimchi once a day, pressing down on the vegetables with a clean finger or spoon to keep them submerged under the brine. (This also releases gases produced during fermentation.) Taste a little at this point, too! When the kimchi tastes ripe enough for your liking, transfer the jar to the refrigerator. You may eat it right away, but it’s best after another week or two.
- Seafood flavor and vegetarian alternatives: Seafood gives kimchi an umami flavor. Different regions and families may use fish sauce, salted shrimp paste, oysters, and other seafood. Use about 2 tablespoons of fish sauce, salted shrimp paste, or a combination of the two. For vegetarian kimchi, you can use 3/4 teaspoon kelp powder mixed with 3 tablespoons water, or simply 3 tablespoons of water.
