1. Differences in epidermis

There are obvious differences between the two varieties, which can be distinguished first from the epidermis. The surface of iron-bar yam is rough, with obvious pores and pimples, dense hairs, and purple spots on the surface. The skin of ordinary yam is generally smooth, the pores and pimples are not obvious, and the hairs are relatively sparse and scattered.

2. Shape Differences

Except In addition to appearance, they can also be distinguished by their shape. Tieguang yam is thinner, only about 1-1.5 cm in thickness, with different lengths, with a round head and a pointed tail. Ordinary yams are relatively thick, about 4-5 centimeters thick, and irregular in shape.

3. Differences in texture

Iron The texture of stick yam is relatively firm, delicate and fine in fiber. It is very strong and does not break easily. Ordinary yams have a lot of water and are very watery. Normally, you can squeeze out the water by pinching it with your hands, but it is easy to break, so you have to be very careful when handling it.

4. Differences in taste

Two There is also a big difference in taste between the two, and it is easy to taste the difference. Steaming or boiling the iron stick yam will take only a few minutes to cook, and it will taste dry and sweet, and will not fall apart after being cooked for a long time. Ordinary yams, on the other hand, remain crisp even if cooked for a longer period of time, so they are often made into a refreshing dish.
