Linzer Torte

The Linzer Torte (or Linzertorte) is an Austrian torte with a lattice design on top of the pastry.[1] It is named after the city of Linz, Austria.
Linzer Torte is a very short, crumbly pastry made of flour, unsalted butter, egg yolks, lemon zest, cinnamon and lemon juice, and ground nuts, usually hazelnuts, but even walnuts or almonds are used, covered with a filling of redcurrant jam or, alternatively, plum butter, thick raspberry,[2] or apricot jam. It is covered by a lattice of dough strips. The dough is rolled out in very thin strips of pastry and arranged to form a criss-cross design on top of the preserves. The pastry is brushed with lightly beaten egg whites, baked, and sometimes decorated with sliced almonds.
Linzer Torte is a holiday classic in the Austrian, Hungarian, Swiss, German, and Tirolean traditions, often eaten at Christmas. Linzer Torte is often made like small tarts or cookies in North American bakeries.
Linzer sablés (German: Linzer Augen, "Linzer eyes") are a cookie-sized version, made by cutting a circle of a similar dough, covering it with jam, placing a donut-like circle with a hole in the center piece of dough on top, and dusting with confectioner's sugar.
