- 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.
- Preheat oven to 350°. In a large bowl, beat egg yolks and water on high speed 5 minutes or until thick and lemon-colored. Gradually beat in 1 cup sugar. Stir in extracts. Sift flour, baking powder and salt together twice; gradually add to yolk mixture and mix well (batter will be very thick).
- Add cream of tartar to egg whites; with clean beaters, beat on medium until soft peaks form. Gradually add remaining sugar, 1 tablespoon at a time, beating on high after each addition until sugar is dissolved. Continue beating until soft glossy peaks form. Fold a fourth of the egg whites into batter, then fold in remaining whites. Spread evenly into prepared pan.
- Bake 15-18 minutes or until cake springs back when lightly touched. Cool 5 minutes. Invert 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. Unroll cake; spread evenly with jelly. Roll up; dust with confectioners' sugar.
