The origin of spaghetti is simply that some people claim that it originated in China, was brought back to Italy by Kyle Poirot, and then spread throughout Europe. It is also claimed that in order to solve the problem of large population and difficult preservation of food, the Roman Empire came up with an ingenious scheme, which kneaded flour into dough, rolled it into pancakes, and then cut it into strips to dry, thus inventing a famous food-pasta. The earliest spaghetti was formed from 13 to 14 century, which is most similar to the spaghetti we ate in 2 1 century. After the Renaissance, the types and sauces of spaghetti were gradually enriched by art.
