Pan di Spagna (Sponge Cake)
The name dates back to the Ottoman Empire, but it can vary by country; English speakers know it as sponge cake.
While it's commonly used for celebratory cakes, the same composition is also used for Ladyfingers, which are featured in desserts such as Tiramisu and Zuccotto. You probably know those dry shelf Ladyfingers, but I don't quite recommend them.
