You will really miss your dad while you are gone.
I had to bing linzertorte as I didn't know what it was.
The Linzer torte is a traditional Austrian pastry, a form of shortcake topped with fruit preserves and sliced nuts with a lattice design on top. 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, raspberry, or apricot preserves. Unlike most tortes, it is typically single layered like a pie or tart. It is covered by a lattice of thin dough strips placed atop the fruit. The pastry is brushed with lightly beaten egg whites, baked, and garnished with nuts.
SO YUMMY!!
