Cranberry Cake Roll

Directions

• Preheat oven to 350°. Place egg whites in a large bowl; let stand at room temperature for 30 minutes. Meanwhile, line a greased 15x10x1-in. baking pan with waxed paper; grease the paper and set aside.
• Add vanilla, cream of tartar and salt to egg whites; beat on medium speed until soft peaks form. Gradually beat in sugar, 2 tablespoons at a time, on high until stiff glossy peaks form and sugar is dissolved. Fold in flour, about 1/4 cup at a time.
• Carefully spread into prepared pan. Bake until cake springs back when lightly touched, 15-20 minutes. Cool for 5 minutes. Turn cake onto a kitchen towel dusted with confectioners’ sugar. Gently peel off waxed paper. Roll up cake in the towel jelly-roll style, starting with a short side. Cool completely on a wire rack.
• For filling, in a large saucepan, combine the cranberries, sugar and 4 Tbsp. water. Bring to a boil. Reduce heat; simmer, uncovered, for 5-6 minutes or until berries pop. Mash berries; strain, reserving juice and discarding pulp. Return juice to the pan and if desired, add chopped candied orange peel, orange liqueur and orange zest. Combine cornstarch and remaining water until smooth; gradually add to cranberry juice mixture. Bring to a boil; cook and stir until thickened, about 2 minutes. Chill.
• Unroll cake and spread filling to within 1/2 in. of edges. Roll up again. Cover and refrigerate for 1 hour before serving. If desired, top with additional confectioners' sugar, candied orange peel and sugared cranberries. Refrigerate leftovers.
