ChicagoLady asked what a "Shrove" was. So, for the benifit of her - and anyone else who's interested - I found this article on the subject... Enjoy!
Shrove Tuesday, in the Christian calendar, the day before Ash Wednesday, which marks the beginning of Lent, traditionally a period of fasting. When Lent was observed more rigorously than it is now, the two or three days prior to Ash Wednesday, known as Shrovetide, were celebrated by games, sports, feasting, dancing, and general merrymaking. “Shrove” comes from the Roman Catholic practice of confessing one’s sins and being absolved of them, or “shriven”. This takes place on Ash Wednesday.
In Germany, Shrove Tuesday is called Fastnacht (Eve of the Fast); in Italy and other southern European countries it is called Carnival (Farewell to Meat); and in Brazil and the United States, Mardi Gras (Fat Tuesday).
Shrovetide feasts were designed to use up the food that could not be eaten during the Lenten fast. In Britain, Collop Monday was when people ate up their supplies of bacon, eggs, and meat and on Shrove Tuesday (now more generally known as Pancake Day) flour, eggs, milk, and butter were used up in the making of pancakes. According to tradition, revelry began with the ringing of the Pancake or Shriving Bell soon after midday, which was the signal for villagers to cease work and go home to make pancakes or join in the games and merrymaking. Pancake Day races are still held in parts of Britain today, as are football matches, played since at least the 16th century when they were rather boisterous games with few or no rules. Other energetic sports were also indulged in, such as hurling and wrestling.
