Ladyfingers are light, crispy and sweet génoise cakes roughly shaped like a large finger. They are called savoiardi in Italian (meaning "from Savoy"), or in French biscuits à la cuillère. In the UK they may be called sponge-fingers, trifle sponges or boudoir biscuits.
Ladyfingers are a principal ingredient in many French dessert recipes. Today, their most common usage is in trifles, charlottes, and tiramisu. They are typically soaked in a sugar syrup or liqueur, such as coffee for the tiramisu dessert.
