Delicious And Refreshing 120g/Packing Wholesale Custom Sponge Cake From Mygou

Sponge cake is a light cake made with egg whites, flour and sugar, sometimes leavened with baking powder. Sponge cakes, leavened with beaten eggs, originated during the Renaissance, possibly in Spain. The sponge cake is thought to be one of the first of the non-yeasted cakes, and the earliest attested sponge cake recipe in English is found in a book by the English poet Gervase Markham.

The basic whisked sponge cake does not contain any fat. It is made by whisking egg whites and caster sugar and gently folding in flour. The process of whisking egg whites incorporates air bubbles to create a foam by agitating the protein albumen to create a partially coagulated membrane, making the egg whites stiffer and increasing their volume. This type of cake, also called foam cake, depends on aeration of eggs and heat to rise. Some types of sponge are baked in ungreased pans to improve the cake's rise by allowing the batter to adhere and climb the sides of the pan. To maintain the moisture of the cake it is sometimes made with potato flour.

For some cakes, like the Victoria Sponge, fat and sugar are creamed before eggs and flour are incorporated into the batter, similar to pound cake. In British English layer cakes like the Victoria Sponge are called "sandwich sponge". This type of buttery cake was not possible without baking powder, which was discovered by English food manufacturer Alfred Bird in 1843, allowing the sponge to rise higher.
