Angel Cake Roll with Creme Chantilly and Orange Zest

This is "Angel Cake Roll" filled with creme chantilly and orange zest.  The recipe came from http://schneiderchen.de/465Angel-Cake-Roll.html   I skipped the Raisins and Blueberry Jam, however.  I like the taste and texture of this cake.  *I used Madagascar Vanilla Paste - if you can see some specs of them.  I have yet to find where to purchase Vanilla powder.

Chiffon Roll Cake

This Chiffon Roll Cake is using most of the ingredients listed for the Strawberry Sponge Cake recipe from Happy Home Baker at http://happyhomebaking.blogspot.com/2007/04/strawberry-sponge-cake.html and some testing I wanted with Cornstarch.
Instead of 140 grams Cake Flour, I used 110 grams of Cake Flour and added 30 grams of Cornstarch. The test result is ... keep on baking. Bo Friberg's explanation of how eggs play their role in sponge cake is noted.
