Genoise cake is a classic French sponge cake known for its light yet slightly dense texture. It is often used as the base for many elegant pastries and desserts due to its ability to absorb syrups and flavors well without becoming soggy. Genoise cakes are typically made using only a few ingredients: eggs, sugar, flour, and sometimes butter for added richness. One of its defining characteristics is how it rises without any chemical leavening agents due to the air beaten into the eggs during its preparation process. This results in a delicate crumb that pairs beautifully with fillings like creams, fruits, or mousses.
