What is "swiss roll"?

Swiss roll is a classic dessert that is made from a thin sheet of sponge cake that is rolled up with a sweet filling, such as jam, cream, or chocolate. The sponge cake is made by whisking eggs and sugar together until light and fluffy, and then folding in flour and other ingredients to create a light and airy batter. The batter is then spread out onto a baking sheet and baked until it is golden brown and springy to the touch. Once the cake is baked, it is removed from the oven and immediately rolled up in a clean kitchen towel to prevent it from cracking. After the cake has cooled, it is unrolled and filled with a sweet filling of your choice. Swiss roll is a versatile and delicious dessert that can be customized with a variety of flavors and fillings. It is a popular dessert for special occasions, such as birthdays and holidays, and can be found in bakeries and pastry shops all over the world.
