Genoise 海绵蛋糕
A genoise (, , , or ; French pronunciation: [ʒenwaz]; Genoese cake or Genovese cake; rarely spelled "génoise" in English) is an Italian sponge cake named after the city of Genoa and closely associated with Italian and French cuisine. Instead of using chemical leavening, air is suspended in the batter through mixing to give volume to the cake. A genoise is not the same thing as a pain de Gênes, which is an almond cake. But a genoise is very close in composition and basic use to a pan di Spagna ("Spanish bread"), another Italian sponge cake.
