Celebrated on January 4th
According to the International Pasta Organization, there are more more than 600 different shapes of pasta produced throughout the world.
A fun origin fact is that on April 1, 1957, BBC made a spoof broadcast convincing everyone that spaghetti grew on trees. At that time spaghetti was considered an exotic delicacy and BBC played on that fact by going into much (facetious) detail about how frost could impair the flavor of spaghetti and that spaghetti strings always grow to the same length. Bonus fact about this television presentation: some people believe it was the first time the television was used to stage an April Fools joke.
Industrially produced spaghetti is 25 centimeters long. Even in a low pot, Italians believe it should never be broken, but added slowly into the boiling water so it can soften, whole.
