Strawberry Nut Roll

Directions

1. 1
   Place egg whites in large bowl; let stand at room temperature for 30 minutes. Line a greased 15x10x1-in. baking pan with waxed paper; grease the paper and set aside.
2. 2
   In a large bowl, beat egg yolks on high speed for 5 minutes or until thick and lemon-colored. Gradually beat in 1/2 cup sugar. Stir in walnuts and break crumbs. Sift flour and salt together twice; gradually add to yolk mixture and mix well (batter will be very thick).
3. 3
   In a large bowl with clean beaters, beat egg whites on medium speed until soft peaks form. Gradually beat in remaining sugar, 1 tablespoon at a time, on high until stiff peaks form. Gradually fold into batter. Spread evenly into prepared pan.
4. 4
   Bake at 375° for 15-17 minutes or until cake springs back when lightly touched. Cool for 5 minutes.
5. 5
   Invert 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. Slice six large strawberries in half; set aside for garnish. Thinly slice remaining berries; set aside.
6. 6
   For the filling, in a large bowl, beat cream until soft peaks form. Gradually add sugar and vanilla, beating until stiff peaks form. Unroll cake; spread filling evenly over cake to within 1/2 in of edges. Top with sliced berries. Roll up again.
