Pancake Day is celebrated in England on February 5th, when English people traditionally make and eat pancakes using ingredients like eggs, flour, milk, and butter. The festival dates back to the 15th century and was a way for Christians to use up foods like eggs and flour before Lent, when some would fast. A fun tradition is tossing pancakes high in the air and trying to flip them before they fall back down. The most famous pancake race is held annually in Olney, England, where participants run while tossing and flipping pancakes.
