The difference between starch and raw flour is similar to the difference between ethanol and alcohol, which can basically be considered as the same thing. Starch is a professional scientific name, and raw flour is a common name among the people, which can be said to be a general term for various starches. According to different sources, starch can be divided into corn starch, wheat starch, potato starch, sweet potato starch, cassava starch, mung bean starch and so on. And starch can basically be extracted from various starch-rich plants.
In daily life, starch is mainly used for thickening, sizing and hanging paste. When scrambled eggs, adding a small amount of water starch (starch mixed with water) can make scrambled eggs more fluffy and taste better. You can also use starch to make your own paste, which is better than the paste you bought when you posted it in spring. The method is to stir the starch with clear water and cook it in a pot until it is transparent. Don't forget to keep stirring when cooking. Tip: Pay attention to the ratio of starch to water. It will be much thicker when it is cold than when it is just cooked. If you try it for the first time, you can add more water. If you feel too thin, you can cook it for a while to remedy it.
Starch also has many uses in industry and laboratory, I don't know. I don't think that's what you want to know, right? Starch, also known as raw flour, is extracted from starchy crops such as lentils, sweet potatoes and potatoes. It is a common material for cooking. Generally speaking, it is thickened with starch.
This dish you are talking about has chicken soup and humidified starch added to make it more tasty (chicken soup is used as broth here), and humidified starch makes the soup thicker.
Thickening is divided into dry starch and wet starch. Dry starch is directly added to vegetables, but the effect is not good and it is not commonly used. Generally, we put dry starch in a bowl and mix it with cold water to make wet starch (also called water starch) to thicken it.
Flour and starch are two different things. Flour contains starch. We use starch instead of flour to add flavor to cooking.
