1. The cream on birthday cakes is usually made from liquid cream that is stirred at high speed until puffed;

2. There are usually three types of cream on the market: the first Animal cream is also called light cream, and it is also the healthiest cream. It is concentrated from the cream extracted from milk and has no sweetness. During the whipping process, you need to add 1:10 sugar to increase the sweetness, that is, add 10g of powdered sugar to 100g of whipping cream. You can also increase or decrease the powdered sugar according to taste. Animal butter is generally more expensive. The second type is vegetable cream, also called hydrogenated vegetable oil and sweet cream. It is usually processed from vegetable oils such as soybeans and water, salt, milk powder, etc. Because it is cheap, stable and easy to operate, it contains a lot of sugar and can be used directly. . Currently, it is commonly used in baking, but vegetable butter contains trans fatty acids that are harmful to the human cardiovascular system, so it is recommended to eat less. The third type is mixed butterfat, which is made from animal butter and vegetable butter in a certain proportion. The price is between animal butter and vegetable butter. It is usually used as animal butter by some small bakeries, so everyone should pay attention to distinguish it.
