How to Make It
Preheat oven to 350°.
Coat a 15 x 10-inch jelly roll pan with cooking spray; line bottom with parchment paper. Coat parchment paper with cooking spray.
To prepare cake, place butter and almond paste in a large bowl; beat with a mixer at medium speed 2 minutes or until blended. Add 1/2 cup granulated sugar, beating until well blended (about 3 minutes). Add eggs, 1 at a time, beating well after each addition.
Lightly spoon flour into dry measuring cups; level with a knife. Combine flour and salt, stirring with a whisk. Add flour mixture to butter mixture, beating just until combined.
Place the egg whites in a large bowl. Using clean, dry beaters, beat egg whites with a mixer at high speed until foamy. Gradually add 1/2 cup granulated sugar, 1 tablespoon at a time, beating until stiff peaks form. Fold egg whites into batter; pour batter into prepared pan.
Bake at 350° for 18 minutes or until cake springs back when touched lightly. Cool. Invert cake onto a wire rack. Remove parchment paper. Cut cake into 4 (10 x 3 3/4-inch) rectangles.
To prepare filling, combine juice and raspberry preserves, stirring with a whisk. Add powdered sugar, stirring until smooth. Reserve 3/4 cup raspberry mixture. Place 1 cake rectangle on a cake platter; spread with 1/4 cup raspberry mixture, leaving a 1/4-inch border. Repeat procedure with remaining cake and 1/2 cup raspberry mixture, ending with cake.
To prepare ganache, combine 1/2 cup granulated sugar, cocoa, and milk in a medium saucepan over medium heat; bring mixture to a boil, stirring frequently. Cook 1 minute, stirring constantly. Remove from heat, and add chocolate, stirring until smooth. Spread ganache evenly over top and sides of cake; let stand 20 minutes or until set. Serve reserved raspberry mixture with torte.
