Granita biscuits, also known as sponge finger biscuits or ladyfingers, are light and delicate cookies that have a sponge-like texture.Granita biscuits are typically made from a few simple ingredients, including eggs, sugar, flour, and sometimes flavorings like vanilla or lemon zest. They are long and finger-shaped, with a slightly crispy exterior and a soft, airy interior. The texture of granita biscuits makes them ideal for soaking up liquids, which is why they are often used in layered desserts where they absorb flavors from creams, syrups, or liqueurs.
