The reason why cucumber is called yellow is because when the cucumber matures, it is mainly yellow, so it is named cucumber. It was also because the taboo was changed from courgette to cucumber.
Cucumber is native to India. It was introduced to the Central Plains by Zhang Qian after his mission to the Western Regions. It was originally called "cucumber" in China, but later during the Five Hus rebellion in China in the late Western Jin Dynasty, Shi Le, a Jie tribe established After Zhao, he felt guilty when he saw "Hu", so he ordered that everyone named "Hu" should be renamed, so "Hugua" was changed to "Cucumber".
In addition to cucumber and courgette, it is also called cucumber and thorn melon.
How to select cucumbers:
When buying cucumbers, the first thing to look at is whether the color of the cucumber is emerald green. The color of naturally grown cucumbers is very shiny green. This is Because there is more sunlight during the growth of cucumbers, photosynthesis is stronger.
As time goes by, the green color will gradually fade, the color will become darker, and the surface will turn a little yellow, which means that the cucumber is no longer fresh. Never buy cucumbers that are stale.
Normally, cucumbers without intervention are slightly curved where they connect to the vines. If when we buy cucumbers, each cucumber is very straight, which must be due to manual intervention. Therefore, when buying cucumbers, try to buy cucumbers with a little curvature.
