Genoise is a light and airy sponge cake originating from Genoa, Italy. It's made by whisking eggs and sugar together vigorously to incorporate air, creating a delicate texture. Unlike some cakes that rely on chemical leaveners, genoise achieves its rise solely from the air beaten into the batter. It's often used as a base for layered cakes, pastries, and desserts. Think of it as the blank canvas of the cake world. It can be flavored with extracts, zests, or liquors to complement other ingredients. The careful technique is key to achieving its signature lightness.
