When I chanced upon this tuber at the wet market, covered in reddish earth, I mistook it for sweet potato.
But the vegetable seller informed me that it is known in Chinese as "xue lian guo". The direct English translation for this is snow lotus fruit.
As it turns out, the tuber is yacon. Native to the Andes, yacon has been the subject of research articles examining its health benefits.
Yacon contains fructooligosaccharides, a form of carbohydrate that is low in calories, and its syrup has been used as a natural sweetener.
Yacon oxidises easily, so it is best to peel it just before use. Or you could squeeze a little lemon juice over it or place it in slightly salted water to prevent it from turning brown after you peel it.
It is refreshingly crunchy and sweet when consumed raw. In texture and taste, I find raw yacon is similar to bang kuang (yam bean, or jicama).
As a soup ingredient, it imparts an aromatic sweet flavour that reminds me of bird's nest soup.
