Cut your cucumber in an "x" leaving about 1 inch from one side. This will create 4 cucumber components while still being connected. Alternatively, you can just cut cucumbers into desired sizes.
9 mini cucumbers
Heavily season the cucumbers with salt and leave them for 20 minutes.
¼ cup kosher salt
Cut chives into 3 inch segments. Cut carrots into 3 inch matchsticks.
1 cup chopped chives, 1 cup chopped carrots
After 20 minutes, rinse off the cucumbers with water and then pat dry with paper towel.
Mix together chives, carrots, grated garlic, grated onion, gochugaru, fish sauce, rice vinegar, sugar, sesame seeds, and sesame oil.
3 cloves garlic, ½ onion, ⅓ cup gochugaru , 2 tbsp fish sauce, 1 tbsp rice vinegar, 1 tbsp sugar, 1 tbsp sesame seeds, ½ tbsp sesame oil
Mix well, and form a paste.
Add this paste to the cucumbers and stuff each one well with the paste.
Place into a container and enjoy.
