The difference between the two is quite obvious.Mao Yam is relatively strong, about 4-5 cm thick, and irregular in shape, some are thin and straight, some curved.The iron stick yam is relatively thin, usually only 1-1.5 cm thick, and the length is uncertain, the head is round and the tail is sharp.
There is also a marked difference in the epidermis between the two.Mao Yam is relatively smooth, the epidermis of the pore lumps and hair is very sparse, showing sporadic distribution.Tiegun Yam epidermis has obvious pore lumps, hair is also distributed more densely, and there are purple spots on the surface.
Mao Yam moisture, more water Ling, can be pinched by hand to pinch out moisture, and easy to break, texture fiber is relatively rough.The iron stick yam is delicate, compact and fine in fiber.It is stronger than the former and is not easy to break.
In addition to the obvious difference in appearance, the difference in taste is also very big.Mao Yam, no matter how long it is boiled, is crisp in taste and is often made into refreshing dishes.And iron stick yam boiled in the pot for 10 minutes, the taste will become sweet, dry noodles, and boiled for a long time.
