The day before Lent is full in most predominantly Christian countries of various celebrations marking the last day of "naughtiness" before we clean up our act, or our kitchens, or our tv habits, or whatever. Christians generally give up something for Lent. For Catholics, this is pretty well prescribed - no meat on Fridays. And thus the origin of the Friday Fish Fry, everyone coming together for a non-meat meal. In most Protestant denominations, individuals choose what they'll give up. Chocolate is a common one. Increasingly, people choose to "fast" from Facebook and things like that. Others add something on - devotions in the morning, exercise routines, time intentionally spent with family, etc.
Yesterday was "Pancake Day" in the UK - the day before Lent, there's a tradition of eating crepes. It's mostly lost its religious significance - but who's going to turn down a crepe!?! In the US, communities celebrate Mardi Gras with a huge party or "Fat Tuesday", eating lots of packzi - donuts made from all the lard, sugar, eggs, and lard not allowed during Lent by Catholic practices in Poland.
So...happy desserts or lack thereof as Lent continues!
