At its simplest, a sponge cake, with the addition of seasonal fruits or berries, some cream or a sweet icing, is one of the delights of home cooking. Even if a sponge comes out of the oven with some imperfection, the fragrant combination of eggs, flour and sugar is enough to get you over the line. With these ingredients you cannot go really wrong.
A custard filling is wonderful with a sponge cake. You might also add some strawberries, either between the layers of the cake or on the side. For something a little more exotic, sprinkle the sponge with a liqueur like Strega or Grand Marnier. Fresh sponge does not need much, but if it is a day or so old it is better to moisturise the sponge with a sugar syrup.
This easy sponge is the basis for countless desserts.
