Because cooking noodles will waste a lot of water, and broth is one of the important components of boiled noodles. If you cook noodles in soup, the taste of soup will soon become less authentic. When cooking noodles, some flour will be left out of the soup, which will affect the quality of the broth. Besides, the noodles are hard to cook and easy to paste. For this, I believe that people who often cook noodles will have experience. No matter whether they are made by machine or by hand, starch will be sprinkled after they are finished. The purpose of this is to prevent adhesion between noodles. When we cook noodles, these flour will be mixed into water, making the water very turbid and white and sticky. If the water used for cooking noodles is not clear water, but broth or water that has been cooked once, Cooking noodles will pollute the stock. Soup stock is prepared by careful collocation, and its original state is the most delicious. If you cook noodles directly in it, the remaining broken noodles and starch on the noodles will directly pollute the soup stock, leading to the rapid change of the taste of the soup stock, which makes the soup stock lose its seasoning value. Soup is very expensive. There are many kinds of soup stock, but most of them are made of animal bones, sinews, etc. It takes more than 8 hours to cook, and there are still many formulas to be prepared, so it is not easy to cook soup stock. It is a magic weapon to make noodles delicious. It is too extravagant to cook noodles directly with soup stock, and it is the most appropriate way to cook them with clear water and season them with soup stock. Convenient for guests to eat. Noodles in soup are usually made fresh. The noodles in soup taste the best, but there is also a disadvantage, that is, it is too hot when it comes out, and diners always feel very hot when they enjoy it, while the prepared broth is in a warm state. Adding broth to noodles can also have a certain cooling effect, which is just good for diners to enjoy noodles. Cooking noodles with clear water is obviously a realistic demand, because if you cook noodles with broth, the noodles will be difficult to cook and easy to paste, cooking noodles will pollute the broth, and pay a high cost, which will also be inconvenient for guests to eat.
