Forbidden fruit is sweetest

Proverbial Meaning: It sometimes seems as though things that we aren't allowed to have are highly desirable and, in fact, these things often are "sweeter" if we do somehow manage to obtain them regardless of obstructing barriers, rules or laws.

Literal Origins: This proverb has its origins in the Christian Bible where Adam and Eve were tempted to eat the "forbidden fruit" in the garden of Eden. One should perhaps note that, though the fruit was indeed very sweet and tasty, they were banished from the garden for eating it.

Common Usage: The proverb is not very common in spoken English as a full sentence, but the sentiment is understood by most. However, many people will simply say 'Forbidden fruit' when describing something that's a little naughty but nice at the same time. This could be anything from eating cream cakes when you're on a diet to fancying a friend's sexy wife or husband.
