A Swiss roll is a type of dessert that consists of a thin layer of sponge cake rolled around a filling, typically made of jam, cream, or chocolate. The cake is baked in a flat sheet, then spread with the filling before being carefully rolled up to create a spiral shape. It is often dusted with powdered sugar or coated with icing. This dessert is popular in many countries and is known by various names, such as Jelly Roll in the United States. The Swiss roll is appreciated for its light texture and versatility, allowing for a wide range of flavor combinations.
