Cut off both ends of the cucumbers. Slice all cucumbers in halves lengthwise.
Using a sharp knife or a spoon, scrape off the seeded part. Only remove the seeds, without cutting off the cucumber flesh.
Afterwards, slice each half in quarters lengthwise, about 3-4 inches long.
Place the cucumbers in a large heat-proof bowl.
In a medium pot, heat up the water and 2 tablespoons of coarse salt. Once boiling, remove off the heat. Pour the hot brine mixture over the cucumbers, the let sit for 2 minutes.
After 2 minutes, discard the brine and wash cucumbers in cold water.
Sprinkle the remaining 1 tablespoons coarse salt over the cucumbers along with corn syrup. Mix well to coat the cucumbers, then set aside for 15 minutes.
Rinse cucumbers in cold water, then place in a sieve to drain off excess liquid.
Clean and cut the chives into 2-inch lengths and slice the onion thinly. Peel and julienne cut the carrots into 2-inch lengths.
Kimchi Paste
Prepare the seasoning ingredients. Mince the garlic, ginger and saeujeot, then puree the Asian pear.
In a small bowl, combine all the ingredients for the seasoning. Mix well to combine into a paste.
Add the onions, carrots and chives into the paste, then mix again to combine.
Mix the paste into the cucumbers, ensuring they are evenly coated in seasoning.
Tightly pack the cucumber kimchi into a jar or airtight container, ensuring there are no air gaps.
Although the cucumber kimchi can be eaten immediately, it can also be fermented for a sharper flavour. Leave at room temperature for 10-12 hours to ferment, then store in the fridge and consume immediately or let ferment for another day for a stronger flavor.
