Kkakdugi or Korean Radish Kimchi

Kkakdugi, or Korean Radish Kimchi, is one of the fastest and simplest kimchis to make. There are relatively few steps and just a handful of ingredients. The recipe you will see here is a little different from others you may find.

Last time I travelled through Korea, I noticed 2 distinct kinds of kkakdugi. One was the classic little cubes served as a side in many restaurants. The other is a much larger and chunkier radish kimchi. This second one accompanies clear and mild beef broth dishes like seolleongtang or doganitang. The pieces of radish tend to be bigger and less uniform and there is much more liquid in the kimchi. The kimchi is on the table in a big container from which you can eat the radish but you can also use the kimchi-juice to season your soup. This is what I am attempting to make here. You can also just eat it as a side the same as you would any kkakdugi.

Ingredients

As a chef, I always preferred to cook by weight rather than volume. I grew up using the metric system and I like it very much. So, as much as possible from now on, I will include metric equivalents. Keep in mind that other than salt and radish, you can vary ingredients as you like to suit your tastes.

  • 3.5-4lb (1.5-2kg) Korean radish (the one i am using is 1700gr)
  • 2 tablespoons (25gr) Diamond Crystal Kosher Salt
  • 1/4cup (30gr) korean chilli flakes / gochugaru
  • 1 tablespoon (20gr) salted baby shrimp / saeujeot
  • 10 cloves (35gr) garlic minced
  • 1 teaspoon (10gr) ginger minced
  • 1 tablespoon sugar (75gr)/syrup
  • 1 asian pear peeled and chopped
  • 1 cup of chopped green onion/scallion or asian chive/buchu

Korean radish is similar to white daikon in some ways but the flavour of Korean radish is usually more sweet and vegetal and less hot and bitter. But, if you really can’t find Korean radish, daikon is a reasonable substitute.

I am using Diamond Kosher salt. You can substitute 30 grams of any good salt, but avoid using table salt.

I just happen to have a homemade maesil plum syrup on hand which I am using instead of sugar. If you want to try it, you can find maesil syrup in any Korean grocer.

Feel free to vary the amount of chilli flakes to make this as spicy or as mild as you like.

Korean pears are not available at this time of year so I am using a whole regular asian pear which is roughly half the size of the Korean variety. You can also substitute an apple or regular pear or leave it out altogether.

Process

raw ingredients for kkakdugi korean radish kimchi
Raw ingredients
chopped Korean radish
Peel and slice radish into disks approximately 3cm/just over an inch thick
Showing the size of the radish pieces after cutting
Use a chef knife to chop the radish into chunks. They don’t need to be the same shape but they should be roughly the same size. As a size guide, you should probably not be able to fit more than one or two chunks on a spoon.
This looks pretty good…
adding salt to the chopped Korean radish
Add the salt and mix thoroughly. You can now let the radish rest for an hour or so. Mix it up every 15-20 minutes moving the radishes on the bottom to the top.

Within just a few minutes, the radish pieces will start to release water.

While you are waiting for the radish to brine, mince the garlic and ginger.

Peel and chop the asian pear. I chose to run it over this Benriner Japanese slicer/shredder.

Put garlic, ginger, pear, salted shrimp, chilli flakes and sugar (or syrup) together in a bowl

Mix them all together
shows how much water the salted radish released
After an hour, the radish has released a good amount of water.
showing the draining of water from the radish
Drain off the radish water and reserve it. Do not rinse the radish.
a measuring cup showing the volume of water released: 250ml/1 cup
I got almost 250ml/1 cup of water out of this radish. I will probably end up adding all of it back as I want this kimchi wet and the radish itself does not taste too salty right now.
Add all ingredients together
radish mixed with seasoning ingredients
Stir them up. Now is a good time to taste the kimchi. The radish will still release a large amount of water so don’t worry if it seems salty now: this will change. Taste for spice..add more chilli flakes if you prefer more heat.
how to chop buchu or scallions
Chop your buchu or scallions into 2cm pieces
adding back released water
Stir the greens back into the radish mix and add back the water
Finished product: here you get an idea of the size of the pieces.

I will let this ferment in a large mason jar on the counter for a day or two until it starts to sour. It is a good idea to put a plate or tray under the jar. The kimchi will expand as it starts to ferment and it may overflow a bit. Also…the bacteria that ferment your kimchi are much happier in the dark. Keep your jar away from sunlight or bright indoor light. I will cover this jar with a towel.

Allow the kimchi to ferment on the counter for a day or two. Taste it a couple times a day and when you are happy with the flavour, refrigerate it. You can eat the radish kimchi as is as a side to any dish or use the kimchi liquid to season mild soups.

Just like any kimchi, kkakdugi will continue to ferment and sour over time. If it gets too sour to eat as is have a look here for ideas on how to use well aged kimchi. Radish kimchi will work just as well as cabbage kimchi in hot dishes. I especially like it in kimchi fried rice.

If you are also looking for a good cabbage kimchi recipe, you can find mine here.

Lastly, if you are interested in what Seolleongtang looks like in Seoul, Korea, have a look here or here. Maybe in the future I will put up a recipe for Seolleongtang although it is a long long process that is challenging to make at home. Here is a good recipe from Korean Bapsang. This kimchi would be a perfect accompaniment!
