THE STORY BEHIND THE IDIOMS

As easy as pie
This expression appeared in the United States in the mid-19th century. Even though it's not easy to make a pie, it's widely known that it is easy to be eaten. The phrase started to be used in literature and became later a part of colloquial language. Nowadays, it's used with the meaning 'very easy'. The first 'as' can also be omitted.
