What is "sponge pudding"?

Sponge pudding is a classic British dessert that is made with a light and fluffy sponge cake that is steamed instead of baked. The sponge cake is usually flavored with vanilla or other flavorings and is often served with a sweet sauce, such as custard or fruit sauce. The pudding is typically made by placing the sponge cake batter into a pudding basin or mold, covering it with a lid or foil, and then steaming it for several hours until it is cooked through. Once cooked, the pudding is turned out onto a plate and served with the desired sauce. Sponge pudding can be made with a variety of flavors, such as chocolate or lemon, and can be customized with different sauces and toppings. It is a comforting and satisfying dessert that is often enjoyed during the colder months, and is known for its light and airy texture and its sweet and indulgent flavor.
