How should I buy yams? How to choose yam correctly

If you just buy yams, regardless of the variety, you can choose them according to the following methods for daily cooking:

In terms of taste, there are two kinds of common yams, one is crispy and the other is more "noodles". We can choose the one that suits us according to different uses.

1. From the appearance, the smoother is the crispy yam, which is suitable for stir-frying; If it is a stewed soup or dessert dish, it is recommended to choose a noodle yam, the taste will be sweet and glutinous, full, and the characteristics of the noodle yam are that there are many pockmarks on the body, many whiskers and smooth.

2. Look at the appearance again. Slightly flattened, with a little curved head, brownish-yellow in color; or the stem is straight and firm; Or in the shape of small hands, they are good yams. If there are raised bumps, the texture may be slightly harder.

3. Then hold it with your hand. Hold the yam for a period of time, the length of time can be determined by the weather at that time, the warmth can be shorter, and vice versa can be longer. After holding and loosening, the skin of fresh yam has a warm feeling; Stale yams will "sweat" and the epidermis will ooze fine droplets, which are frozen yams.

Once the yam has been frozen, the content of polysaccharides and free amino acids in the mucus will be damaged, and the nutritional value will be reduced and the taste will be poor.

4. When buying, you can break a little skin, or look at the yam cutting surface, the meat is white, and the juice is viscous is fresh yam; When the frozen yam is cut, the flesh inside is red like rust, and it has a hard heart, and the juice is like water.

It is said that there are as many as 350 kinds of yams, including Huai Yam, Huai Yam, Ma Yam, Vegetable Yam, Mao Yam, Light Yam, and Foot Plate Root; The origin of yam is also considered to be accessible from north to south, and there are yam planting areas in Henan, Shandong, Hebei, Hunan, and Guangdong.

As a member of the potato family, the identity of yam is different from that of other potatoes such as potatoes, sweet potatoes, cassava, taro, etc., because it can be used in medicine, and it has become a "medicine and food" food with both medicinal and edible beauty, which is suitable for long-term consumption in all seasons.

The best yam species is the iron stick yam.

The best yam production area is Jiaozuo (formerly Huaiqing Mansion) in Henan, and the local yam is called "Huai Yam".

Therefore, the best yam is naturally the iron rod yam! Among them, the quality of the yam is one layer higher.

In addition, the yams of Shandong Heze, Hubei Wuxue, Hubei Gucheng, Jiangxi Ruichang and other real estate are also famous for a long time.

There is no heart line in the middle of the yam slices, whereas there is a heart line in the middle of the tapioca chips, and although the heart line is small, it can be seen if you look closely. Some cassava chips are thinly shaved, and after drying, the heart thread tends to fall out, but if the heart thread falls off, it will leave a small hole. If there is a small hole in the middle, it must be cassava chips.

The skin of the yam is very thin and is peeled clean before slicing. Whereas, tapioca skin is much thicker than yam skin. Some cassava the size of a thumb are too small to peel and difficult to peel, and counterfeiters often don't bother to peel them, so after they are cut into dry slices, thick skins remain on the edges.

Whoever has thick skin will be a false yam.

Dried yam slices contain a lot of starch, and when you touch it with your hands, it feels more delicate, and there will be more starch sticking to your hands. Although cassava also contains a lot of starch, it has more crude fiber than yams, and it feels coarser to the touch than yams, and there is less starch left on the hands.

Yams are generally easy to boil, whereas cassava is difficult to cook. The boiled yam has a rotten, powdery texture, while cassava has a harder texture.
