This international holiday originated in Sweden and is called Våffeldagen and coincides with the Feast of the Annunciation. This day was also considered the start of spring in Sweden and Europe. It became a custom for Swedish families to celebrate the two events by making waffles on this day. The waffle dates back to the 1300s in Greece. Greeks cooked flat cakes between two metal pans. At the time, they topped it with cheeses and herbs. Pancake syrup wasn't around back then. Waffles are commonly eaten as breakfast or a snack. They are also an occasional dinner meal for some people.
