I am a big fan of cooking shows, especially those on baking. I found this recipe a few months ago from Cake Boss & now it's all I use for my sponge cakes. The secret to this cake being Light & Fluffy is the beating of the eggs. Don't rush that step.
Victorian Sponge Recipe via The Stone Soup... includes helpful tips for getting the correct batter consistency as well as how to substitute for self-rising flour. I'll be making this recipe "open-faced" with just one layer of sponge cake.
