In social life, people agree that the food we eat must be made by hand or machine, but is this really the case? There is no doubt that it is not. In fact, in our life, many foods are made with feet. Everyone thinks that food is clean as long as you wash your hands. Would you still accept it if it were feet? Even if you don't accept it, I believe you have eaten all the following foods. These foods are not made by hand, but stepped on by feet. Everyone ate the last one!

The first kind: mustard tuber

This is a meal recognized by many people, and they all think it tastes good. When drinking porridge or eating steamed bread, a dish of mustard tuber is indispensable, which is twice as refreshing, but most people don't know that the mustard tuber we eat is actually stepped out with our feet, because in the curing process, stepping on it with our feet can make the mustard tuber dehydrate better, which makes the mustard tuber taste better and easier to preserve.

The second kind: wine

This wine is very popular in China in recent years. I believe many people will have a few bottles at home. In fact, the brewing process of wine has to be stepped on by feet, because stepping on grapes with feet can keep its original taste, and the brewed wine is more pure and delicious. Of course, it is also very particular in the process of stepping on grapes, so stepping on grapes is also a technical activity.

The third kind: salt

I believe there is no one who hasn't eaten this. After all, we have to eat every day, and there must be salt in the food. Many people only know that salt is extracted from seawater, but they don't know that the production process is stepped out with their feet. Salt is first turned out of the salt pond and then stepped on it to dry. Therefore, the salt we eat is inseparable from stepping on it with our feet.
