Shrove Tuesday is the day before Ash Wednesday (the first day of Lent). Shrove Tuesday is widely associated with feasting and celebrations, like Fat Tuesday or Mardi Gras. The idea behind it is that we celebrate and get “fat” before we enter into the penitential season of fasting.
Pancakes have always been associated with Shrove Tuesday. This is because it was a quick and easy way to use up foods like eggs, milk, and sugar, before the fasting season of Lent started. To fast was to eat plainer food and refrain from foods of pleasure, such as meat, dairy, or eggs.
So, if you are reading this, find a local church and go eat some pancakes!
