Which is better, iron stick yam or common yam?
Among many varieties of yam, iron stick yam is one of the most valuable medicines and the most suitable tonic in autumn. Compared with common yam, iron stick yam is thinner and shorter, with longer burrs at the root, rounded head and tail and delicate cross section.
And iron stick yam is more delicious than ordinary yam. Iron stick yam is the most valuable yam in many Chinese medicines, and the taste of iron stick yam is much better than ordinary yam.
In terms of length, iron stick yam is generally less than meters long and two fingers thick. It is compact and tough, and it is not easy to break when colliding with each other, hence the name "iron stick yam". Because it is short and thin, it is generally sold as a whole.

How to choose authentic and delicious iron stick yam
When selecting iron bar yam, we try to choose iron bar yam with dense roots, rusty color and heavy weight. This iron yam is the best variety of iron yam.
Look at the roots
What we need to see is whether the root of iron stick yam is thick. For us, when buying yam, we always choose some smooth yam. If yam has many roots, many people will think it looks particularly scary.

Look at the weight
It's just two iron yams about the same size. Let's compare their weights, just like we usually buy grapefruit or cantaloupe.
Under the same size, the heavier the better. Because the heavier instructions are rich in water, the lighter instructions are not fresh. If the water evaporates, it will taste bad.
