National Fruitcake Day

National Fruitcake Day, a December 27 holiday, is today. This day celebrates the rock-hard, fruit-filled holiday cake. While this heavy and overly sweet cake was popular in the 40s and ’50s, we are not sure if anyone has ever eaten this weighty, gooey, sugar-laden cake.

Scientists have been unable to penetrate deeply into a fruitcake, and therefore, have failed to uncover its exact composition. Its density has also hampered its ability to use carbon dating to identify the age of a fruitcake. Unconfirmed rumors suggest that some fruitcakes are hundreds, if not thousands, of years old.
