According to Wikipedia:
"The festival is widely associated with the eating of foods such as pancakes, and often known simply as Pancake Day, originally because these used up ingredients such as fat and eggs, the consumption of which was traditionally restricted during Lent. ...In the United Kingdom, Shrove Tuesday is often known colloquially as Pancake Day or Pancake Tuesday. The traditional pancake is slightly thicker than a French crêpe. It is served immediately after preparation and was traditionally served with a meat-based stew, although in modern times a sprinkling of granulated sugar (fine sugar in the United States), or caster sugar (superfine sugar in the United States), and lemon juice has become more common. Many other sweet and savoury toppings are used today (for example, in Canada pancakes are often served with maple syrup or preserves)."
So, in honor of the day, IHOP is giving away free pancakes and raising money for charity.
I'm very excited about this, and will visit them as soon as I leave.
...But I just have to be careful not to get TOO excited.
