Really Rich Revani Cake_The Ultimate Greek Sponge Cake_Its often been said that making a sponge cake is like a science. Eggs have to beaten for a certain amount of time. Flours have to be sifted and weighed. Deviating from the formula can often bring mixed results. Well, today I have a little treat for you in the form of a Greek sponge cake. Its called revani and I think I may like it more than the karydopita I made. Like my lime, yoghurt and olive oil cake this revani cake is full of happiness.
