Sponges
Sponges are made from three main ingredients: eggs, sugar and flour with some containing a small amount of butter as well.
Classically made sponges (Genoise) do not contain baking powder or baking soda. Their volume and light texture come solely from the air whipped into the egg and sugar solution.
Genoise Sponge
Genoise sponge is an Italian sponge cake named after the city of Genoa and associated with Italian and French cuisine. Instead of using chemical leavening, air is suspended in the batter during mixing to provide volume. It is a whole-egg cake, unlike some other sponge cakes for which yolks and whites are beaten separately. The eggs, and sometimes extra yolks, are beaten with sugar and heated at the same time, using a bain-marie or flame, to a stage known to patissiers as "ribbon stage". A genoise is generally a fairly lean cake, getting most of its fat from egg yolks, but some recipes also add in melted butter before baking.
