The key to crossing the bridge rice noodles lies in a bowl of soup, which is very particular. Besides pig bones, two strong hens and an old duck must be used as raw materials. Some people say, can't I use three strong hens and two old ducks? No way! This is the chef's accumulated experience for many years, so that the soup cooked is fresh and must be an old duck! Chickens and ducks should be slaughtered now, and the chicken blood should be kept. Boil pig bones and chickens and ducks for four or five hours with strong fire. Take out all the things in the soup, crush the chicken blood and put it into the soup, and keep stirring. At this time, chicken blood will condense the impurities in the soup, and the soup will change from milky white to clear and bright. Remove the sediment, then add the pig bones and simmer for an hour or two. Nowadays, rice noodle shops generally do not use this technology. In order to ensure that customers can see that their soup is really stewed with pig bones and chicken, (many soups don't use old ducks, but use feed chickens produced by chicken farms) the color of the soup is deliberately kept milky white. If milky white is not enough, throw a tube of "bait block" (also a food made of rice in Yunnan) into the soup as white as possible. Gee, it was a slip of the tongue. This is one of the secrets of cooking today! It makes me want to eat. . . Tony, the chef in karma, I don't want to pursue the historical origin of rice noodles. Let me report to you. The result of my experiment just now is that the soup is very thick, but it is not the taste of rice noodle soup I want! ! ! Lack of fresh flavor! ! ! ! Tony from karma: I used to eat a lot of rice noodles when I was in Kunming. Basically different stores have different tastes. There is no absolute standard. Guilin rice noodles are all the same, and I think snail powder basically tastes the same! Strawberry girl, dear, sour bamboo shoots are only available in Liuzhou snail powder. Come to Guilin to eat. And Guilin rice noodles, don't call them rice noodles.
