Some Catholic feast days have food associated with it. Sometimes the food goes a tad overboard on the symbolism. Behold! St. Lucy pastries! The only dessert you can have a staring contest with!
More traditionally are the "Lucy Cats" which are made in Sweden. They are, as the internet and some liturgical Advent materials say, delivered by young girls with candles in their hair on this day. The cakes, visibly (haha! pun!), are made in the image of eyeballs.
You think this is bad? Wait til you see what people do for St. Agatha's Day!
