"In the Christian calendar, Shrove Tuesday is the English name for the Tuesday before Ash Wednesday, which in turn marks the beginning of Lent. In many solidly Roman Catholic countries in Europe and the Americas, this is the last day of Carnival. In some historically Francophone places it is Mardi Gras, French for "Fat Tuesday"; the most famous celebration under this name is the New Orleans Mardi Gras.
The origin of the name Shrove lies in the archaic English verb "to shrive" which means to absolve people of their sins. It was common in the Middle Ages for "shriveners" (priests) to hear people's confessions at this time, to prepare them for Lent.
In Ireland, Australia, and Canada, Shrove Tuesday is known as "Pancake Tuesday", while in Britain it is popularly known as "Pancake Day."
I think that New Orleans needs to work the pancake angle into our Mardi Gras celebrations. The Krewe of Zulu has its coconuts so why not add pancakes into the mix?
