Recipe for Kkakdugi (깍두기) - Cubed Radish Kimchi

© 2016 Kotokami LLC
  • About 1½-2 Liters (1½-2 Quarts)
  • Preparation:
  • Cooking:
  • Waiting:


  • 30g (3T) Mochiko (Sweet Rice Flour)
  • 240g (1 cup) room temperature Water
  • 3 Joseon Radishes (roughly 6 inches in length and 3 inches in diameter)
  • 25-30g (4-5t) Kosher Salt
  • 3 medium Scallions
  • 3-4 (9-12g) cloves Garlic, minced
  • 6g (1T) Ginger, minced
  • 18g (1T) Fish Sauce
  • 20g (1T) Salted Fermented Shrimp
  • 45-50g (about ½-cup) Red Pepper Flakes
  • 12g (1T) Granulated Sugar


  • Put the Mochiko into a small saucepan with 120g (½-cup) of water. Stir with a spatula and let it sit for 10-15 minutes.
  • Once the flour looks hydrated, place it over a medium flame. Stir constantly while cooking. As it begins to thicken, lower the flame. Slowly add the rest of the 120g (½-cup) of water, about 30g (2T) at a time, making sure the water is well incorporated before adding more.
  • Continue stirring on a low flame. The rice mixture will thicken and become translucent. Stir for another minute.
  • Turn off the heat and set aside to cool to room temperature.
  • As the rice paste is cooling, rinse and trim the radishes, getting rid of any brown spots and stray roots and stalks. Cut the radish into 1-1½ inch cubes, and place into a large bowl.
  • Add the salt and toss until the salt is well incorporated. Set aside for 1½ hours, or until the salt has brined the radishes.
  • While the radishes are brining, wash the scallions and cut them into lengths of 1½ inches. In a small bowl add the cut scallions, garlic, ginger, fish sauce, shrimp, red pepper flakes, and sugar. Add the cooled rice paste and mix all of the ingredients together. Set aside.
  • Rinse the radishes and drain well. Add the seasoning and rice mixture into the large bowl. Mix thoroughly.
  • Taste-test and see if the kimchi needs more fish sauce or salt. It should be quite briny and salty, like a cucumber pickle.
  • Place all of the radish cubes into a 2-quart container and make sure there aren't any large air pockets.
  • Cover and set aside for about 2-3 days at room temperature. Afterwards, place into the refrigerator for about 1 week before eating.

*Bunny Wisdom*

  • Hydrating any kind of fine powder requires a little bit of patience. The resting period allows the dry ingredient to absorb the water, preventing large flour pockets.
  • Take care to lower the heat if the mixture seems to be thickening faster than it is possible for you to incorporate the rest of the water.
  • The continuous stirring prevents sticking and burning on the bottom of the saucepan.
  • You will notice the mixture will go from opaque to translucent. Simmer for a minute, stirring and watching slow bubbles surface like the Bubbling Mud Pots of Yellowstone National Park. You don't want it to be boiling.
  • Flip the radish cubes halfway through the brining stage. This will help distribute the salt and the saltwater created at the bottom of the bowl. You are welcome to rinse and taste a piece at this stage to see if it's salted well. The rinsed radish should taste salty; not just on the exterior, but the inner parts should be well-seasoned.
  • You can find all of the ingredients at your local Asian or Korean grocery store.
  • Level out the kimchi inside the container, making sure there aren't any large open spaces.
  • If you are making this in the Summer, it may only take 1-2 days before you have to place the container into the refrigerator. The warmth of temperature affects the duration of fermentation. If you begin to notice a lot of bubbles forming and the kimchi rising upwards, pop open the container to release the gas, push the kimchi down, cover, and refrigerate. For this reason, I place my kimchi into a container that has a bit of breathing room on top.
  • You can eat this as early as you want, but the more complex savory flavors begin developing in the second week and after.
  • Any kimchi that seems quite stinky, fermented, and sour can be used in other recipes! Consider making Kimchi Stew (김치 찌개 - kimchi jjigae), Kimchi Soup (김치국 - kimchi guk), or Kimchi Fried Rice (김치 볶음밥 - kimchi bokkeumbap). Don't throw it away!
