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. The cookies, which originated in Ancient Roman cuisine, are found in several traditional European cuisines. Angel wings are known by many other names and have been incorporated into other regional cuisines (such as American cuisine) 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" (Mardi Gras), the day before the start of Lent (Ash Wednesday). 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.
