Kkakdugi is a type of kimchi made with Korean radish ("mu" in Korean). Kkakdugi pairs well with soups like seolengtang (ox tail soup) and noodle soups but it can be enjoyed with any meals. The seasoning for kkakdugi is very similar to that of napa cabbage kimchi. But, Kkakdugi has a more refreshing flavor and a crunchy texture because of the characteristics of Korean radish.

You can vary the amounts of gochugaru (red chili flakes), sugar and fish sauce to your liking.

Optional Ingredients and Substitution

Shrimp fish sauce: For Kkakdugi, shrimp fish sauce is better than other types of fish sauce because it keeps the refreshing taste which is key to Kkakdugi. Also, other types of fish sauce can darken the color. However, some Koreans use anchovy sauce only or a mix of shrimp fish sauce and anchovy fish sauce.

Korean radish (mu): Contrary to popular belief, Korean radish is actually slightly different from daikon. They belong to the same species called R. sativus but are different varieties. You can use daikon instead of Korean radish but keep in mind that it will have a slightly different taste and texture than that of authentic Kkakdugi.

Good to Know

Amount of Kkakdugi
The default serving amount of this recipe calls 1 large Korean radish. Usually ¼ large Korean radish is good for a meal for 4 people.
(1 large napa cabbages = 16 servings. If 2 people eat Kkakdugi once a day, it will last 1-2 weeks.)

Use rubber gloves!
Use clean food-safe rubber cloves for brining cabbages and applying seasoning. Otherwise, your hands will sting from salt and chili peppers.

Seasoning Leftover
If you have made more seasoning than you need, you can freeze the seasoning. When you make kkakdugi next time, thaw the seasoning in the fridge overnight and use it. Also, you can use other types of kimchi with your favorite vegetables such as cucumber, soybean sprouts, garlic chives, green onions, etc.

Frequently Asked Questions

Do I have to use coarse sea salt?
You can use kosher salt. But, coarse ones are better than fine ones. If the particles are too small, it may speed up the brining process too much that the texture of Kkakdugi may not be as crispy. We don’t recommend using table salt (iodized salt) because iodine prevents fermentation and the texture and the color of Kkakdugi may not turn out right.

You can buy coarse sea salt from local Korean market or order online here.

How long should I ferment Kkakdugi for?
Fermentation time depends on temperature and the amount of salt in the Kkakdugi. A lower temperature and smaller amount of salt will make the fermentation process slower. The duration of fermentation also depends on your personal preference. Some people like fresh (almost unfermented) kkakdugi. Some like it very fermented and sour.

I personally like my kkakdugi fermented to medium sourness. I leave it out in room temperature for about 2 days. The best way is to leave it out and taste it every day. When it reaches your preference, put it in the refrigerator. If you made a large amount, you can leave some out and store the rest in the fridge right away. Then, take some out later for more fermentation as needed.

Remember that kkakdugi will produce gas and liquid as it is fermented. Leave some room in the container, or it will overflow.

How should I store my kkakdugi and how long does it last?
Traditionally, kimchi (including kkakdugi) was stored in earthenware called "Ong-gi." Ong-gi (Onggi) is breathable pottery that keeps kimchi and other fermented foods in an optimal condition. Today, most Koreans use plastic or stainless containers to store Kimchi, and keep the containers in a specialized Kimchi fridge. Kimchi fridges keep kimchi at an optimal temperature, and keeps your regular fridge free of the potent kimchi smell.

If you don't have any of the above, place the kimchi in a tightly sealed container and keep in the fridge.

When you place kkakdugi in a container, make sure you press down firmly to get rid of any air between kkakdugi. Then, cover the top with a plastic sheet or saran wrap before closing the lid. (This is only necessary if you are making a large amount and storing it for months.) Finally, make sure the lid is on properly.

Kkakdugi can last 2-3 months or longer in the fridge but it may get sour in taste.

1. Peel radish

Peel Korean radish(es) with a peeler. Quickly rinse them to remove any dirt. Some Koreans leave the skin on for texture and nutrients. If you want to leave the skin on, wash thoroughly using a scrub before using.

3. Season

In a large bowl, throughly mix the coarse salt with cubed radishes. Let it sit for about one hour. During the one hour, mix it around every 20 minutes so that the radishes are evenly seasoned.

(mix it up every 20 min)

4. Wash & drain

Wash the seasoned radishes in a large bowl of water three time each time with fresh water. At this point, it should taste a tiny bit saltier than you like. The saltiness will decrease as they get fermented later. If it’s extremely salty, wash more to desired to saltiness. Leave them in a strainer for at least 1 to 2 hours to drain water out completely.

6. Make gochugaru paste

Add gochugaru (hot pepper flakes) into the flour soup. (If you can’t take very spicy food, reduce the amount of gochugau. Mix well. Leave it for about 20 min to get more vibrant color (optional).

10. Place in container

Place them in a container with a good seal. Do not completely fill the container and place a tray below the container. It can overflow as it produces liquid while fermenting. Once the container is filled, use your hand to pat down on kimchi so that it is tightly packed in the container.

11. Cover

Cover the top with a plastic sheet (cling wrap). Close the lid. If you are making a small amount and will be eating it in a week or two, you don’t have to cover with a plastic sheet. The plastic sheet keeps the air out so it reduces a chance of getting molds. Alternatively, you can use a specialized kimchi container or fermenter with a vacuum seal. You can buy the container here.

12. Ferment

Leave it out in room temperature for a day or two for proper fermentation until it has a sour taste you like. (If you are not eating it soon, refrigerate immediately. Then, leave it out a day of two when you want to ferment it further.) If you have time, you can ferment the kimchi slowly in the refrigerator but this can take a few weeks.

13. Store

After they are fermented, keep them in the fridge. Kkakdugi lasts for a few weeks when refrigerated. You can keep it longer but it may taste too sour. Kkakdugi tends to be fermented faster than napa cabbage kimchi.
