What makes sponge cake different from most other types of cake is its less fatty recipe. The recipe for pound cake for example can contain 25% fat, but the sponge cake is made with very little fat or no fat at all, other than what is in the egg yolks. The result is a cake with much lighter eating properties, which makes it a perfect base for adding creamy fillings. You can find all equipment components to produce this very finely structured cake in the TFT range of production lines. The process starts with mixing the ingredients and buffering them. Then the cake batter is continuously aerated to the required density.
