In ancient times, every meal of the emperor was very luxurious and varied, and the emperor often could not finish it. At this time, some people were very business-minded, and they made profits by selling the emperor's meals.
In ancient times, the emperor's meal was a top priority. Many dishes that should not be neglected were always hot. If the emperor wanted to eat them, he had to serve them, and he would be punished if he was not careful.
There are so many dishes every day that the emperor can't finish them. What should he do? Sometimes when there are ministers in the palace, they will eat with them, and most of the time there are still a lot left. In ancient times, some restaurants would say that their chefs came from the imperial kitchen, which would attract many customers to taste. But in fact, it's not because they have a chef in the imperial kitchen, but what the emperor can't finish, and they are sold out of the palace for profiteering.
There are many people involved in selling what the emperor can't eat to the people, because it is easy to get money. Selling the seemingly good leftovers of the emperor to a restaurant, and then the restaurant sells them at a high price, how many times the price has to be doubled. Those leftovers that don't look good are sold to people outside the palace at low prices. These people mix these dishes with porridge and sell them to some ordinary people. Although the price is not expensive, they are still delicious.
although this matter is not on the table, it will not waste food, so that a large number of leftovers of the emperor need not be thrown away. In ancient times, food was still scarce, so that some people who could not eat could fill their stomachs.
In a word, what the emperor could not finish was not directly thrown away, but was disposed of and sold outside the palace, which was a tacit thing for many people at that time.
