Linz is the reputed home of the renowned Linzertorte. A Linzertorte is a tart made of a rich buttery dough accentuated by almonds, lemon zest, and cinnamon. The tart is traditionally filled with black currant preserves and topped with a lattice crust. In America, raspberry has replaced black currant as the jam of choice. Linzertortes are a traditional European Christmas pastry, a custom that is now enjoyed in the US as well.
