Qifeng cake [q Ο f ē ng] is a transliteration of English Chiffon Cake, which belongs to sponge cake type and has a very light texture. It uses vegetable oil, eggs, sugar, flour and baking powder as basic materials. Because vegetable oil is not as easy to foam as butter (traditional cakes are made of butter), it is necessary to foam the egg whites to provide enough air to support the size of the cake. Qifeng cake contains enough vegetable oil and eggs, so the texture is very moist, not as easy to harden as traditional butter cake. Qifeng cake also contains less saturated fat. However, due to the lack of rich flavor of butter cake, Qifeng cake usually needs rich juice or chocolate, fruit and other ingredients.
