Vanillekipferl

Vanillekipferl are Austrian, German, Swiss, Czech, Slovak, Polish and Hungarian small, crescent-shaped biscuits. They were originally made with walnuts, but almonds or hazelnuts can also be used. They get their typical flavour from a heavy dusting of vanilla sugar. Vanillekipferl originate from Vienna in Austria and are traditionally made at Christmas. They are very well known in Europe and are often for sale in Viennese coffee shops and bakeries, especially during Christmas time. They are said to have been created in the shape of the Turkish crescent moon symbolizing the celebration of the victory over the Turkish in 1683 at the Battle of Vienna. They are also widely baked in Germany and are common in Switzerland, Hungary, Poland, Croatia, Czech Republic, Romania, Slovakia and among the Danube Swabian diaspora as a part of the typical Christmas baking. Since Advent in Germany is celebrated by several denominations of Christianity on the four Sundays preceding Christmas, many kinds of biscuits and sweets are consumed during this time and have become typical for winter.[citation needed]
