Preheat oven to 350 F. Line a 15 X 10-inch jelly roll pan with parchment paper, set aside. Crack the eggs & separate the whites into a mixing bowl. Set whites aside to warm to room temperature.
Measure flour, cornstarch & 1 cup powdered sugar carefully into a large bowl. Whisk together; SIFT the flour mixture into another large bowl then SIFT mixture back into first bowl and then again into the second bowl ( you are sifting the mixture 3 times ). Set aside.
Whip the egg whites with a mixer on medium speed until foamy. Add the cream of tartar & salt; continue whipping on high speed until soft peaks form. While continuing to whip on medium-high speed, add the 1/2 cup powdered sugar slowly – about 2 Tbsp at a time – until fully incorporated. Increase the speed to high & whip until hard peaks form, adding the extracts as it whips.
Using a wire whisk, fold the flour mixture into the whipped egg whites about 1/4 cup at a time, making sure to fold very gently & slowly, so as not to deflate the egg whites. This is a critical step, so take your time.
Pour batter into prepared pan & smooth out top carefully. Bake for 25-30 minutes or until cake springs back when touched lightly in center. Cool cake for 5 minutes in pan; turn out onto a dish towel dusted with powdered sugar. Carefully peel off parchment paper, cool for 1 minute & cut off crisp edges of cake. Starting at narrow end, roll up cake & towel together. Place seam side down, on a wire rack & cool for 5 minutes.
Lemon Cream Filling
WHILE CAKE IS BAKING, combine the pudding mix & milk together in a bowl. Chill to set up for 20 minutes. In another bowl, beat together cream cheese & lemon zest until smooth. Stir in the ‘set’ pudding & chill again until cake is ready to fill.
Balsamic Strawberries
Slice the strawberries & place in a bowl. Add balsamic vinegar, extract (or Chambord liqueur), honey & salt. Combine & set aside.
Assembly & Serving
Carefully unroll cake & spread the filling over entire cake. Again roll up as tight as you can; place on a piece of plastic wrap & roll up tightly. At this point you can either place your cake roll in the freezer overnight or chill it in the refrigerator for a few hours before cutting & serving. Top with some balsamic strawberries.
Recipe Notes
If time is short, prepare a one-step angel food cake mix instead of the ‘scratch’ cake.
