While this is easy to make, it may take a bit of experimentation with your oven to determine the best temperature and to perfect the timing two elements that are critical for the success of this sponge cake. Every oven is slightly different to another, be guided by your oven manufacturer’s instructions. As a guide, the second shelf up from the oven floor is usually the best position for the cake pan and the temperature should be 200°C in a fan-forced oven. Gentle folding of the water and flour mixtures through the egg mixture is also important for success heavy handling of the mixture equals a heavy sponge cake. storage Cake is best made on the day it is served.
