Notes
Italians don't usually add salt but you could add a couple of pinches and whisk with the dry ingredients.cake. You could also substitute the vanilla with your favourite flavouring.Make sure your eggs are at room temperature, so take them out of the fridge 45-60 minutes before using.For this cake I used an Italian 00 flour which has a protein count of about 10 percent. I also added some corn starch to give the cake a soft and tender crumb.Do not open the oven door before 25-30 minutes. If you do the cake could very well fall.If you prefer you can add the zest of a lemon or orange to the cake. You could also substitute the vanilla with your favourite flavouring.
A sponge cake will remain soft for about 2 days. To keep it soft be sure to wrap it in plastic wrap and store it at room temperature.The baked cooled cake should be wrapped in plastic wrap and placed in an airtight container or freezer bag, it will keep in the freezer for up to one month. If you don’t have a big enough bag or container then wrap the cake in foil.In order to thaw the cake, place the cake on a wire rack and leave it to thaw at room temperature. It should take a couple of hours to thaw. Once it has thawed it should be covered or it will start to dry out and go stale.
