Make two perpendicular cuts at the stem of the Napa cabbage. Then split the head into TWO separate pieces with your hands. (We will split it again into four pieces later - not now)

Give both cabbage pieces a thorough wash under running water. Place the cabbage in a large plastic basin or mixing bowl. 

Then grab a few pieces of Kosher salt (not dining salt!) and sprinkle salt between each layer of cabbage. Focus the salt near the white stems where it is thick. Salt the other piece as well. (Note: You will use a total of ½ cup of kosher salt for both pieces)

Now split each cabbage again into four pieces. This will makes it easier to fit into your large basin or mixing bowl. 

Then get a ½ cup of water. And pour it over all four cabbage pieces. Cover your mixing bowl or basin with a lid and set it aside for 6 hours. (This salting will kick off the fermentation process).

After 3 hours, rotate the bottom cabbage piece to the top. (This ensures that each piece spends some time in the salty water at the bottom of the bowl).

While you wait, skip to the next section...  

Take out a mixing bowl. Measure 1 cup of gochugaru and add it in. Next, we will prep the other fresh ingredients.

Skin the potato. Then cut the potato into smaller pieces. Place into a microwave friendly bowl. And cover with plastic wrap. Poke a few holes. Then cook in microwave for 3 minutes. 

Next, peel the onion. Cut the ½ piece into smaller pieces. Skin the apple. Core the apple and cut into smaller pieces. Next, peel off the garlics. Set aside 15 cloves. Next, skin off the ginger. Cut off a ping-pong sized piece. 

Place the potato, onion, apple, garlic and ginger pieces into a large blender. Then blitz it smooth until it becomes the consistency of mashed potatoes. (Note: Make sure to check that there are no big chunks!)

Now add the potato mix into the bowl with the gochugaru. 

Next, add the saeujeot into the mix. (Pro-tip: Blitz the saeujeot in a blender before adding to the mix - this will make the small shrimp invisible in the kimchi later) 

Add 1 Tablespoon of sugar.

Add 1 Tablespoon of sesame seeds

Then mix everything together with a spoon. 

Place this spicy Kimchi paste into the refrigerator - let it chill down. 

Before we make the salad, let's finish off the Napa Cabbage leaves... 

After 6 hours of soaking, the Napa leaves will turn limp. Try bending the stem and it should bend without snapping. (If it snaps, place in salt water for longer.)

If ready, thoroughly wash each of the four cabbage pieces under running water. Get in between each leaf and wash off all of the salt.  

Then give 3-4 good squeezes to each cabbage. (Note: Don't squeeze it completely dry - just a few good squeezes). Then set it aside in a colander and let it drip-off excess water. 

Trim stems off each green onion. Split each green onion stalk near the white stems. Then cut the green onion into finger-length pieces. 

Peel the Korean radish. Dice small sections. Then julienne into thin small strips (refer to video).

Take out a large mixing bowl. Now place in the spring onion and Korean radish pieces.

Take the Kimchi paste out of the refrigerator. Mix-in half of it into the spring onion and radish salad. Give it a thorough mix with your hands. Top-off with sesame seeds. Set aside for next step.

Take each Napa cabbage - that has been soaking off excess water. Then get a dab of Kimchi paste and apply it to each layer of the cabbage. (Don't put too much Kimchi paste - we will add the radish salad too)

After you apply the kimchi paste, grab a few pinches of the spicy radish salad. Add a few pinches in between each layer of leaf as well. Repeat for all four cabbage pieces. 

Make sure to coat the leaf tips at the end as well.

Add each finished Kimchi piece into a Tupperware. Sprinkle a few coats of sesame seeds. Place lid on. 

Set the Tupperware aside at room temperature. Let it sit out for 24 hours. (Note: This step speeds up the fermentation process and ages the Kimchi)

After 24 hours, place the Tupperware in the refrigerator. Once its turns cold, cut it and eat as you please!
