The Chinese discovered steam and used it to steam steamed buns. Westerners discovered steam more than a thousand years later and invented the steam engine. But I have never thought of using it to steam food. Westerners don’t have buns or steamed buns because they don’t know how to “steam” things.

In European dining habits, meat and vegetables are either eaten raw, grilled or boiled. In addition to roasting it in the fire, it is roasted on a stone slab on the fire, and then it is boiled in water. As for the cooking method of "steaming", it is basically influenced by Asians and gradually started to be adopted in the West. Eating methods such as steamed pork with rice flour, braised pork with pickled vegetables, and steamed fish are unlikely to have appeared in ancient Europe.

Probably few people have thought about why rice can be eaten as a whole grain, but wheat has to be made into flour and is rarely eaten whole.

This is because wheat grains have a tight structure and contain more substances that affect digestion, making them more difficult to digest than rice grains.

Whole wheat grains are quite unfriendly to the digestive tract. If you don’t believe it, just buy wheat grains, cook them and eat them.

After the domestication of wheat, there was a tradition of grilled pasta, which is still maintained by Westerners today. Why do they make bread and we make steamed buns, steamed buns, and dumplings? One is because of the cooking method, and the other is because they have milk in nomadic areas. Therefore, this difference caused them to evolve in the direction of bread. After our ancestors returned, they developed various types of pasta. Steamed buns and dumplings are the continuation of ancient steamed buns. Zongzi is an ancient snack that was invented because of the lack of cooking utensils. So wrapping things into rice noodles has been around for a long time. The male ethnic group has always had a tradition of wrapping things into rice noodles. So with wheat noodles, it is normal to wrap things in wheat seedlings. Just like rice dumplings, they are not originally pyramid-shaped, as you can see in Vietnam. But ours is pyramid-shaped, which may be related to the returned Qiang culture.
