식은 죽 먹기
Like eating cold rice porridge
Used to express confidence in one's ability to do something.
죽 is a watered-down rice gruel that Koreans often eat when they are sick since it is easy to eat and digest. It is Korea's version of the American chicken-soup remedy. Even though 죽 is easy to eat, it is even easier when it is cold since one does not have to worry about scalding the inside of one's mouth.
