Sponge cake is a kind of puffy pastry which is made by filling a large amount of air into the egg liquid and adding flour to bake. It is named for its structure similar to porous sponge. Non fat cake is also known as cake. Sponge cake is made of eggs, sugar, flour and a small amount of grease. In the cake making process, the protein is reduced by high speed agitation to reduce the surface tension of globulin and increase the viscosity of the protein. Because of the large viscosity components, it helps to form the initial stage of the foam, so that it can quickly penetrate into the air and form a foam. Globulin and other proteins in the protein are slightly denatured by the mechanical action of agitation. Denatured protein molecules can be condensed into a layer of skin. A very firm film is formed to encircle the mixed air. At the same time, because of the surface tension, the protein foam is contracted into a sphere. The protein colloid has viscosity and the added flour material adheres around the protein foam.

Cooking tips:I think the ultimate meaning of the delicious cake roll is that the cake body must be soft and delicate. The most excellent one is the one with tender fragrance and soft entrance. My new excellent helper, Panasonic nujk180w automatic baking machine, has successfully solved this problem. The principle of this one-piece steaming and baking machine is the steaming and tender baking technology, which makes the cake roll not lose water while baking. Not only that. This machine can be used for one machine, eight functions. It can steam, bake, stew, fry, make yoghurt, defrost, microwave heat, and disinfect. Just one of them can meet most of my family's needs in the kitchen ~ and I have to say, the face value of this oven is really high.. The external devices are touch-screen keys. The light appearance doesn't take up space. But it's 20L and has two layers. It's enough for home baking. I am particularly satisfied. So I sincerely recommend it to you.. It's the most valuable kitchen electricity I bought in 2019.. Link here - htt
