Su bak in Korean means watermelon.
Have anyone of you notice that all most 90% of Korean restaurant will serve watermelon as desert? I noticed that when i visit to the restaurant.
Why? Asked my Korean uncle, he said Korean love to eat watermelon and it's season fruit in Korea!
Here i found some recipe specially for watermelon, want to try?
