Our community has been closed for two days. I used to order takeout every day because of my busy business, but now I can finally cook a few meals for myself. Looking at the vegetables I bought, well, cabbage, Brassicaceae, peppers, Solanaceae, winter melon, Cucurbitaceae, and coriander, Umbelliferae, it seems that these are the vegetables we usually eat.

What fascinates me the most is the Solanaceae family, you know? Tobacco, tomatoes, potatoes, peppers, nightshades, datura and eggplants are all related to the same family. Plants in the Solanaceae family have one thing in common: they all have a certain degree of toxicity or other flavors that you cannot tolerate. For example, tobacco leaves contain nicotine, green tomatoes contain solanine, sprouted potatoes and potato seedlings also contain solanine, and peppers contain solanine. Capsaicin, datura is the king of poisons, and eggplant contains solanine.

Special potatoes are an alternative to the Solanaceae family. Potatoes are native to South America and were brought to Europe during the great voyages of the 16th century. Potatoes are now a relatively important food for Europeans and Americans, but when they were first brought to Europe, Europeans did not understand potatoes and many people were poisoned. The chef of Queen Elizabeth I made a dish with potatoes. All the nobles who ate the dish were poisoned. It turned out that he threw away the potato tubers and used potato shoots instead.

Later, Europeans learned to eat potato tubers, but accidentally ate sprouted and green potatoes and became poisoned. Potatoes were introduced to our country in the late Ming Dynasty and were first called potato. Its shape looks very much like a bell on a horse's neck, so it is also called potato. Soon it was widely planted in Hebei, Inner Mongolia, Shanxi, and northern Shaanxi. Potatoes have a large output. If they could have been introduced 50 years earlier, the Qing Dynasty might not have had anything to do with it. It can only be said that the Qing Dynasty took advantage of it. Then in the early Qing Dynasty, our country's population increased all at once (of course, there were also sweet potatoes, corn and other American products. food credit). In areas such as northern Shaanxi and Shanxi, the arable area is very small, and it is all stony mountainous land. Potatoes are a relatively easy crop to grow and are easy to store.

People will dry the potatoes, leaving more starch, and then beat them and turn them into glutinous rice cakes as the staple food. In the Yan'an area, potatoes have always been used as a staple food. When potatoes sprout, they will produce solanine, so even if we eat potatoes regularly, as long as they sprout and turn green, we must not be reluctant to throw them away. If we are afraid of waste, we will buy less. First, it is fresh, and second, it saves money.
