💡 How To Make Kimchi Step By Step
Making your own kimchi at home is a transformative culinary experience that connects you to a centuries-old tradition of preservation and flavor.
I remember the first time I watched my auntie massage vibrant red chili paste into salted cabbage leaves, the spicy and pungent aroma filling her sunlit kitchen.
After years of trial and error in my own kitchen, I have refined this process to help you achieve that perfect balance of crunch, spice, and tang every single time.
Quick Overview
This guide will take you through the traditional method of making Baechu-kimchi, which is the most popular variety made with napa cabbage.
- Time needed: 4 hours of active prep, plus 2 to 5 days for fermentation.
- Difficulty: Intermediate
- What you’ll need: Napa cabbage, Korean radish, coarse sea salt, glutinous rice flour, Gochugaru (Korean chili flakes), fish sauce, ginger, garlic, and glass jars.
Step 1: Prepare the Cabbage
Select two large heads of napa cabbage that feel heavy for their size and have crisp, green outer leaves.
Trim the very bottom of the cabbage root, but keep the base intact so the leaves do not fall apart immediately.
Slice a slit about two inches deep into the base of the cabbage and then gently pull the halves apart with your hands.
Repeat this process on each half to create quarters, ensuring the leaves stay attached to the core for easier handling during the salting phase.
Pro Tip: Pulling the cabbage apart by hand rather than cutting all the way through with a knife preserves the natural leaf edges and prevents small, shredded bits.
Step 2: The Salting Process
Dunk each cabbage quarter into a large bowl of water to get the leaves wet, which helps the salt stick more effectively.
Sprinkle coarse sea salt between every single leaf, focusing more salt near the thick white stems where the cabbage is densest.
Place the salted quarters into a large basin or a clean plastic bucket to sit for about two to three hours.
Rotate the cabbage every thirty minutes, moving the pieces from the bottom to the top to ensure they all brine evenly in the extracted moisture.
Check for readiness by bending a thick white stem; if it bends easily without snapping, the cabbage is sufficiently softened and ready for the next stage.
Step 3: Rinse and Drain Thoroughly
Rinse the cabbage quarters under cold running water at least three times to remove all traces of excess salt and any hidden dirt.
Squeeze the leaves gently to remove as much water as possible without bruising the vegetable structure.
Drain the cabbage in a colander for at least thirty minutes, cut-side down, to ensure the final kimchi is not watery or diluted.
Pro Tip: If you skip the thorough draining, your kimchi paste will slide off the leaves instead of sticking to them, resulting in a bland finished product.
Step 4: Make the Rice Porridge Base
Whisk two tablespoons of glutinous rice flour into one and a half cups of water in a small saucepan over medium heat.
Stir the mixture constantly until it begins to bubble and transforms into a translucent, thick paste that resembles a light porridge.
Add two tablespoons of brown sugar or white sugar to the hot mixture and stir until it dissolves completely.
Remove the pan from the heat and let the porridge cool down to room temperature before you attempt to mix it with the spicy ingredients.
Understand that this porridge acts as the “glue” for your spices and provides the necessary sugars for the healthy bacteria to feed on during fermentation.
Step 5: Prepare the Aromatics and Vegetables
Mince half a cup of garlic and two tablespoons of fresh ginger until they form a fine paste.
Chop one medium-sized onion into very fine pieces or pulse it in a food processor until it is almost liquid.
Slice a pound of Korean radish (mu) into thin matchsticks, about two inches long, to add crunch and a refreshing bite.
Cut a bunch of green onions and a handful of Asian chives into two-inch lengths to provide a mild onion flavor and visual contrast.
Julienne a large carrot into thin strips if you want extra color and a hint of natural sweetness in your ferment.
Step 6: Mix the Kimchi Paste
Combine the cooled rice porridge with the minced garlic, ginger, and onion in a very large mixing bowl.
Pour in half a cup of high-quality fish sauce, which provides the essential umami depth that defines traditional kimchi.
Incorporate one to two cups of Gochugaru, depending on your heat tolerance, and stir until the mixture becomes a thick, vibrant red paste.
Add the radish matchsticks, carrots, and green onions into the paste and toss them well until every piece is coated.
Pro Tip: For a vegan version, replace the fish sauce with a mixture of soy sauce and kelp powder to maintain that savory “fifth taste.”
Step 7: Coat the Cabbage Leaves
Wear disposable food-prep gloves to protect your hands from the intense heat of the chili flakes and the lingering smell of the garlic.
Spread a generous amount of the spicy paste onto every single leaf of the cabbage quarters, starting from the outermost leaf and working your way in.
Ensure that the thick white parts of the stems receive a good coating of the radish and spice mixture, as these parts take longer to flavor.
Fold the leafy end of the cabbage quarter back toward the root end to create a neat, compact bundle that is easy to pack.
Step 8: Pack the Jars
Place the coated cabbage bundles into clean glass jars, pressing down firmly with your fist to eliminate any air pockets.
Leave at least two inches of headspace at the top of the jar, as the kimchi will expand and release juices as it ferments.
Wipe the rim of the jar with a clean, damp cloth to remove any stray paste that could encourage the growth of mold.
Seal the jars with a lid, but do not tighten it excessively, as the gases produced during fermentation need a way to escape.
Step 9: The Fermentation Phase
Sit the jars in a cool, dark place out of direct sunlight for one to three days to kickstart the lacto-fermentation process.
Press down on the cabbage with a clean spoon once a day to keep the vegetables submerged in their own brine.
Taste a small piece of the cabbage after twenty-four hours to check the flavor profile.
Transfer the jars to the refrigerator once the kimchi tastes pleasantly sour and the cabbage has reached your desired level of tanginess.
Pro Tip: Kimchi ferments much faster in warm weather, so keep a close eye on it during the summer months to prevent it from becoming overly sour.
Common Mistakes to Avoid
Using Iodized Table Salt
Table salt often contains iodine and anti-caking agents that can inhibit the growth of the beneficial bacteria needed for fermentation. This can result in a bitter taste or a ferment that never actually starts. Always use coarse sea salt or specific Korean pickling salt for the best results.
Failing to Drain the Cabbage
If the cabbage is still dripping with water when you apply the paste, the moisture will dilute the spices and create a thin, watery sauce. This prevents the flavors from penetrating the vegetables properly. Patience during the draining phase is the key to a thick, rich kimchi sauce.
Packing the Jars Too Full
The fermentation process creates carbon dioxide, which causes the liquid levels in the jar to rise. If there is no headspace, the spicy brine will leak out from under the lid and create a significant mess on your counter. Always leave enough room for the “breath” of the ferment.
Troubleshooting
The Kimchi is Too Salty
If you find that your kimchi is overwhelmingly salty after the first day, do not panic. You can add more un-salted radish matchsticks or even a few slices of raw onion to the jar. These vegetables will draw out the excess salt and help balance the overall flavor as they ferment.
A White Film Has Formed on Top
A thin white film, often called Kahm yeast, can sometimes appear on the surface of the liquid if the vegetables are exposed to air. This is generally harmless and can be scraped off, but it often indicates that the environment is too warm or the seal isn’t right. Ensure your vegetables stay submerged under the brine to prevent this from happening.
The Cabbage is Mushy Instead of Crunchy
Mushy kimchi is usually the result of over-salting or fermenting at a temperature that is too high. If the cell walls of the cabbage break down too quickly, the texture becomes soft and unappealing. To prevent this, ensure you rinse the salt off thoroughly and move the jars to the fridge as soon as the tanginess develops.
Key Takeaways
- Preparation is paramount: Properly salting and draining the cabbage dictates the final texture and shelf life.
- Use authentic ingredients: Gochugaru provides a specific smoky heat that cannot be replicated by standard chili flakes or cayenne pepper.
- The porridge matters: The rice flour paste is the secret to getting the spices to cling to the leaves and feeding the fermentation.
- Manage the air: Pressing the cabbage down to remove air pockets prevents spoilage and encourages a healthy ferment.
- Trust your taste buds: Fermentation is a living process, so let your palate decide when the kimchi is ready for the refrigerator.
Frequently Asked Questions
Can I make kimchi without fish sauce?
Yes, you can easily make a vegan version of this recipe. Substitute the fish sauce with an equal amount of high-quality soy sauce, or create a concentrated broth using dried shiitake mushrooms and kelp. This provides the necessary savory depth without using animal products.
How long does homemade kimchi last in the fridge?
When stored in an airtight container in the refrigerator, kimchi can last for six months or even longer. Over time, it will continue to ferment slowly, becoming more sour and softer in texture. Older, very sour kimchi is highly prized for use in stews and fried rice.
Why does my kimchi smell so strong?
The combination of garlic, ginger, and fermented seafood naturally creates a very pungent aroma. During the fermentation process, gases are released that can be quite intense when you open the jar. This is completely normal and is a sign that the healthy bacteria are doing their job.
Do I have to use napa cabbage?
While napa cabbage is the standard, you can apply this same fermentation technique to many other vegetables. Radishes, cucumbers, and even scallions make excellent kimchi. Each vegetable requires slightly different salting times, but the spice paste remains relatively consistent.
Our Top Recommended Finds
- Glass Fermentation Jars: Look for wide-mouth mason jars or specialized Korean “E-jen” containers that have an inner vacuum lid to keep the cabbage submerged.
- Premium Gochugaru: Seek out sun-dried Korean chili flakes for the most vibrant color and a complex, smoky flavor profile.
- Fermentation Weights: These small glass discs sit on top of the vegetables inside the jar, ensuring everything stays below the brine line to prevent mold.
