What green beans are · young pods of the bean family

Stop 1/8

豆角是什么 · 豆科的嫩荚

Sijidou, doujiao, yundou and caidou are the same thing: the young pods of the common bean (Phaseolus vulgaris), eaten pod and all before the seeds harden. It is a close relative of red beans, black beans and chickpeas, but eaten very differently.

It is a staple vegetable on Chinese home tables: dry-fried green beans, beans with braised noodles, stir-fried green beans. North China says doujiao, the south says sijidou or yundou; dried beans winter-store for stews.

The knowledge worth remembering lives in special-knowledge: raw green beans are toxic, but the toxin fears heat. Chinese home cooking (high-heat stir-fry, blanched quick-fry) is exactly the high-risk setting, and the reason is unpacked there.

Nutritionally it is a classic low-calorie vegetable: watery, fibrous, low-sugar. Later scenes quantify per 100 g.
