The difference between iron stick yam and ordinary yam

1. Epidermal Difference

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

2. Shape Difference

In addition to appearance, they can also be distinguished by shape. The iron stick yam is thinner, only about 1-1.5 cm thick, with varying lengths, a round head and a pointed tail. Ordinary yam is relatively thick, about 4-5 cm thick, and has an irregular shape.

3. Texture Difference

The texture of iron stick yam is relatively firmer, delicate and fine-fibered. It is very strong and won't break easily. Ordinary yam is high in moisture and very juicy. Normally, water can be squeezed out of it with your hands and it is easy to break, so you have to be very careful when handling it.

4. Difference in taste

The taste difference between the two is also very big, and it is easy to taste the difference. It only takes minutes to steam or boil the iron stick yam, which has a dry and sweet texture and does not fall apart even after a long cooking. Ordinary yam remains crisp even if cooked for a longer time, so it is often made into refreshing dishes.
