The specific tuition fees vary greatly, ranging from a few hundred to tens of thousands, mainly depending on what kind of people you meet. The simplest truth to understand here is that the most expensive is definitely not the best. As far as making cold noodles is concerned, the technology is very simple, and if you really find a good master in a few steps, you can master it all in a day or two, which is not as profound and complicated as many people think.

White material in the flour water is starch, and gluten remains in the basin. The freshly washed noodle water can't be directly used to make cold noodles, mainly because the noodle water is too thin, and the cold noodles can't be formed and need to be precipitated. In the process of learning cold noodle technology, we should not only understand the specific operation essentials of each step, but also understand the function and purpose of this step in cold noodle making. You can ask questions For example, the main purpose of dough proofing is to make the gluten in dough more sticky and lay a good foundation for the next separation. If the dough is not properly proofed, gluten starch will be difficult to separate, and washing failure will occur in severe cases. The main purpose of washing your face is to separate starch and gluten. You can't make cold noodles without washing your face. The main purpose of precipitation is to separate the excess water in the noodle water and increase the consistency of the batter to meet the needs of making cold noodles.
