Angel wings are a traditional sweet crisp pastry made out of dough that has been shaped into thin twisted ribbons, deep-fried, and sprinkled with powdered sugar. Common to many European cuisines, angel wings have been incorporated into other regional cuisines by immigrant populations. They are most commonly eaten in the period just before Lent, often during Carnival and on Fat Thursday, the last Thursday before Lent—not to be confused with "Fat Tuesday", the day before the start of Lent. There is a tradition in some countries for husbands to give angel wings to their wives on Friday the 13th in order to avoid bad luck.
