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.

Ingredients
- 3 lb Korean Radish 1 radish is about 2-3 lb or 0.9-1.36 kg
- 3 tbs Coarse Sea Salt We use Korean coarse sea salt. Depending on what type and grain size you use, the amount may vary. If you are using finer salt, you will need more.
Seasoning
- 1½ tsp Sweet Rice Flour or regular all purpose flour
- ½ cup Water
- ⅓ cup Gochugaru (Korean Hot Pepper Flakes) This recipe is on the spicy side so cut gochugaru by 20-30% if you want medium spicy.
- 2 tbs Salted Shrimp (Sae Woo Jeot) Can be found in refrigerated section of Korean market. Can use anchovy fish sauce instead OR use half salted shrimp & half anchovy fish sauce
- 3 Green Onion cut 1" length
- 1 tbs Sugar or artificial sweetener or use minced apple
- 4 tsp Garlic minced
- ½ tsp Ginger minced
- 1/4 tsp Coarse Sea Salt (OPTIONAL) Only if your seasoning is not salty enough you can add some salt as needed (because salted shrimp saltiness may vary depending on the brand)
Instructions
- 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 lb Korean Radish
- Cut the radishes into bite-sized cubes (¾” x ¾” x¾” or 2cm X 2cm X2 cm).
- 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 at 30 min mark so that the radishes are evenly seasoned. (The colder the temperature, the longer the brining time.)3 tbs Coarse Sea Salt
- Wash the seasoned radishes in a large bowl of water 1-3 times (depending on the saltiness), each time with fresh water. At this point, if you taste after washing, should be a tiny bit saltier than you like. The saltiness will decrease as they get fermented later. If it’s extremely salty, you can soak in water for a while until desired to saltiness.
- Leave them in a strainer for at least 1 to 2 hours to drain water out completely.
- Mix sweet rice flour (or regular flour) with COLD water. Stir until there are no lumps. (If you are making a large amount, use some water to mix with flour and boil the rest of the water. Then, add the mixture to the boiling water. This way you don't have to stir for a long time.) Cook on medium heat while stirring until it reaches “cream soup like” consistency. Take it off the heat and let it cool completely.1½ tsp Sweet Rice Flour, ½ cup Water
- 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). If you leave this gochugaru and flour soup mixture in the fridge overnight, it can improve color and taste but not required.⅓ cup Gochugaru
- In a medium bowl, mix all remaining ingredients (salted shrimp, green onions, minced garlic, minced ginger and sugar) into the gochugaru paste. Taste and add some salt as needed ONLY IF your seasoning is not salty enough you can add some salt (because salted shrimp saltiness may vary depending on the brand OR if your brined radish is not salty enough)2 tbs Salted Shrimp (Sae Woo Jeot), 3 Green Onion, 1 tbs Sugar, 4 tsp Garlic, ½ tsp Ginger, 1/4 tsp Coarse Sea Salt (OPTIONAL)
- In a large bowl, throughly mix the radish cubes with the seasoning. Don’t pour all the seasoning at once in case there is too much seasoning for the amount of radish.
- Place them in a container with a good seal. Fill only 85% of 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.
- 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.
- Leave it out in room temperature for a day or two for proper fermentation then into the fridge. If you want to eat it soon you can leave it at room temperature until it has a sour taste you like. We left out in room temperature for 4 days before eating it.
- After they are fermented, keep them in the fridge.
- Serve COLD as a side dish (usually 5-10 pieces per person).
Notes
Good to Know
Optional Ingredients and Substitution Salted Shrimp: Salted shrimp can be found in the refrigerated or freezer section of Korean markets. Store in the freezer to keep it for a long time since only a small amount is used at a time. Due to its saltiness, it doesn't freeze solid so you can use it anytime without thawing. For Kkakdugi, salted shrimp is better than other types of fish sauce because it keeps the refreshing and clean taste which is key to Kkakdugi. Also, other types of fish sauce can darken the color. However, some Koreans, especially in the southern Korea, 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. Amount of KkakdugiThe default serving amount of this recipe calls 1 large Korean radish. Usually ¼ large Korean radish is good for a meal for 4 people. 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 3-4 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 kimchi 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 very large amount and storing it for months.) Finally, make sure the lid is on properly. White Kkakdugi can last for many months, it tastes best to eat within a month. If you keep it longer than 1 month, it will get too sour. Unlike napa cabbage kimchi, kkadugi is NOT meant to be fermented and eaten for a long period of time. Kkakdugi tends to be fermented faster than napa cabbage kimchi.
