WATER KIMCHI may not really sound appetizing but it is absolutely refreshing and delicious. And it’s quite simple to make.

Water kimchi really doesn’t involve a lot of ingredients but it comes out so fabulous – so refreshing and belly cleansing deliciousness. There’s a phrase that Koreans use to describe a taste sensation like this – “속이 확 뚤린다” – which basically means it feels like my stomach is totally clearing. I guess a similar feeling would be how you feel when you drink sparking water or any bubbly drinks. You can feel it reach the deep area of your stomach in a very clearing way.
Korean Water Kimchi (mul kimchi 물김치) is traditionally served as part of a Korean meal as banchan (side dish) but recently, especially in more fancy restaurants, they are served almost as apértif – as a way to stimulate your appetite.

Served as part of a meal, I feel it acts as a way to cleanse your palette in between heavily fatty or spicy dishes.
By the way, this recipe was done at late afternoon time and so I decided to make it outside since that would give me more day light. Some pics may look darker than usual but better dark than later, right?? HAHAHA
OH! OH!! NEWS FLASH!! I have just uploaded my very FIRST recipe video!! I am not 100% happy with it but it’s my very first one so hope you are going to be gentle with me about it… 😍 Video is at the very end of this post.
Before we go onto the recipe, I want to clarify exactly what Mul Kimchi is. Because it’s actually a very general term and that includes many different kinds. First, “mul” literally means “water”. And according to the Korean Food Science and Technology Dictionary, Mul kimchi has radish and Korean napa cabbage as its main ingredients but can have many other vegetables. It is made by adding lightly salted brine that is not spicy.
Here are some common kinds of water kimchi (mul kimchi) :
- Dongchimi (동치미) – made from whole radishes (winter)
- Nabak Kimchi (나박김치) – made from cut radish and napa cabbage. Lightly colored with fine red chili powder (spring, summer)
- Jang Kimchi (장김치) – different vegetables seasoned with soy sauce (jang) only (summer)
- Yeolmu Mul kimchi (열무물김치) – made with young radish greens (summer)
- Sangchoo Mul Kimchi (상추물김치) – made with lettuce (summer)
- Oi Mul Kimchi (오이 물김치) – made with cucumbers (summer)
So I have to say, my Water Kimchi recipe here is sort of in between a Dongchimi and Nabak kimchi but is probably the most popular version in modern Korean cuisine because it is simple to make and yet captures the best flavors of Mul Kimchi. Now, normally, the liquid of Korean water kimchi made with radish is colorless but I decided to go a little different and added watermelon radish for some pretty color. And boy, was I glad I did!! The color came out such a pretty pink and the watermelon radish tasted quite crunchy and delicious too! I LOVE this recipe.
** PREVENT SLIMY KIMCHI!! — Please follow the recipe closely and be careful not to leave the kimchi in too warm a temperature in the summer to prevent it from getting slimy. Read more about it HERE on how to prevent your water kimchi from getting slimy or jelly-like.

Water Kimchi (Mul Kimchi)
Ingredients
- 1 large Korean radish
- 1 watermelon radish
- 1 bunch water dropwort (minari) – optional
- 1/2 Korean pear
- 1/2 yellow onion
- 6 garlic cloves
- 3-4 Korean green chili peppers (or 2-3 Jalapeno peppers)
- 3-4 Korean red chilis or other mild chili peppers like Piquillo de Lodosa
- 2 fresh ginger slices (1/8 inch thick)
- 1 bunch green onions
Kimchi water
- 2 liter (1/2 gallon) water
- 4 Tbsp Korean Solar Sea Salt (Cheonilyeom 천일염)
- 1 Tbsp sugar (for now)
- 1 large plastic container (4 liter / 1 gallon size)
Instructions
- Peel and cut 1 large Korean radish into 1.5 in (1.75 cm) thick chunks –> cut each thick round chunk vertically into 0.5 in (1.2 cm) thick slices –> and then each slice into 0.5 in (1.2 cm) thick batons
- Peel and cut 1 watermelon radish into slices (approx 1/4 in or 0.5 cm thick) and then into quarters.
- Core 1/2 Korean pear and peel and cut 1/2 yellow onion.
- Wash and cut 1 bunch water dropwort into 2 in (5cm) lengths. Discard leafy parts on top and also bottom thick stems that are too fibrous. Wash and take off stems from 3-4 Korean green chili peppers and 3-4 Korean red chilis or other mild chili peppers like Piquillo de Lodosa.
- Prepare 2 fresh ginger slices and6 garlic cloves. Cut 1 bunch green onions into 1/2 lengths.
- Place all of the ingredients in container in no particular order but would be good to have the bigger items like pear and onion at the bottom.
- Mix 4 Tbsp Korean Solar Sea Salt and 1 Tbsp sugar in 2 liter (1/2 gallon) water. Stir until everything is well dissolved.
- Pour salt sugar water on top of the Kimchi ingredients prepared in container.
- Water kimchi is now ready for fermentation. LEAVE at room temperature for 1 day. On a HOT summer day, you may want to put in the fridge sooner. Refrigerate for 2-3 days and it will be fabulous!! As it ferments, you will taste somewhat of a fizzy taste which is just so awesomely refreshing.
Tips & Notes:
- At time of serving, add about 1/2 tsp sugar (adjust to taste) per 1 cup of water kimchi
- Weight of my radishes (both regular and watermelon radish) was about 1 kg.
- Water or Mul Kimchi is best served COLD straight from the fridge. You can also add 1-2 ice cubes right before serving.
- If you like things sweeter, you can add a little more sugar (1/2 tsp per 1 cup) right before serving. I made the recipe on the less sweet side so that you can adjust to your liking.
- Use leftover water kimchi liquid to make the most delicious cold soup for noodles. You can make naengmyeon noodle soup with it. Just add some beef or chicken broth to it.

Notes
- PLEASE use Korean Cheonilyeom Solar Sea Salt for Kimchi. If you don’t have a Korean grocery nearby, you can find it online or find under Basic Korean Seasonings category in my Amazon store. If you are going to use other sea salt, please add to taste as they tend to make things more salty than Korean salt.
- Total weight of my radishes (regular and watermelon radish) was about 1 kg or 2.2 lbs.
- Water or Mul Kimchi is best served COLD straight from the fridge. You can also add 1-2 ice cubes right before serving.
- If you like things sweeter, you can add a little more sugar (1/2 tsp per 1 cup) right before serving. I made the recipe on the less sweet side so that you can adjust to your liking.
- Use leftover water kimchi liquid to make the most delicious cold soup for noodles. You can make naengmyeon noodle soup with it. Just add some beef or chicken broth to it and season with vinegar, sugar and soy sauce.
- To add extra fizziness, sometimes my mom adds sprite or 7 up before servings. Probably 1-2 Tbs or so to each serving.
- This kimchi should last up to a month or so in the fridge – especially if you put it in the fridge a little early (leave at room temp only for 1/2 day instead of 1 day).

Hi JinJoo, I love so many of your recipes — but may I suggest updating the salt/sugar amounts in the instructional steps (step 8 with photos / step 7 in text) as well? Unfortunately, I followed that part with the old amounts and missed your footnote at the end, so I ended up with the slimy kimchi. 🙁 I’m so bummed, it looked delicious when prepping and I was so looking forward to trying it and sharing with my family who all love 물김치! Hopefully I can find all the ingredients again and give it another try.
Hi CJ, my sincere apologies!! I thought I updated in all the necessary places but I somehow missed the part. I just updated it.. I really hope you can find the ingredients and try again. Note, the watermelon radish is mainly for color so not really necessary. Thank you so much for letting me know.
This recipe is sooooo good! It’s light & refreshing, perfect for summer. I would skip the watermelon radish because 1. It’s hard to find and 2. It’s a bit pricey for radish and 3. The beautiful color of the watermelon radish will slowly fade because of the kimchi water. Traditional little red radishes work as well. I omitted the minari and Korean pear (hard to find) and used an additional green onion and regular pear. Worked out well!!
