Because the planting conditions of Ruichang yam are extremely harsh, it is suitable for planting on the high hillside at an altitude of 3-5 meters, and it has strict requirements on soil, water quality and climate (Ruichang yam is suitable for planting in the micro-area with neutral or alkaline limestone soil and a soil depth of more than 8 cm). In addition, Ruichang yam is a rotation plant. After planting for one year, it will take three to five years before planting again. Moreover, the yield of Ruichang yam is low, only about 1 kg per mu. Therefore, the price of Ruichang yam is higher, which is 3 to 4 times that of ordinary yam. In recent years, Ruichang yam has been sold as a high-grade gift at home and abroad, and appeared on the dining tables of some high-grade hotels, while authentic Ruichang yam is rarely seen in supermarkets and vegetable markets.
The price of Ruichang yam is so high that many foreign yams have entered the Ruichang market and sold under the name "Ruichang Yam", which seriously damaged the reputation of Ruichang yam. Ruichang yam is obviously different from foreign yam in appearance. Ruichang yam has a rough skin and many root hairs. The foreign yam is smooth and straight, with few root hairs, which can be seen at a glance. Only the authentic Ruichang yam produced in Ruichang City, Jiangxi Province, tastes authentic. As the saying goes, "Oranges born in Huainan are oranges, and those born in Huaibei are oranges" is the truth.
judging from the shape of yam, Ruichang yam is irregular. Due to soil, water quality, climate and other reasons, Ruichang yam only grows one to two feet long and two inches wide, with brown color and whiskers all over. "I am ugly, but I have a lot of connotation", which is a true portrayal of Ruichang Yam. Ruichang yam is different from Huai yam and Tiegun yam in the north, and its thickness is not equal, and it is not necessarily straight and vertical, and some of them are bifurcated or slightly black spots, which is normal. Don't look bad, but it's delicious! But also does not affect the nutritional components of Chinese yam. The cooked Ruichang yam is non-paste, moderate in hardness, without silk in the middle and excellent in taste. Unlike ordinary northern yam, it looks stout and beautiful, but it is not delicious. If anyone has the chance to eat the real Ruichang yam, you will be full of praise.
The common yam or iron stick yam is basically long, regular, not far apart in size, with sparse and long hair, dry skin, dull color and some brownish red. It is easy to paste after cooking, and some of it is silky. In the words of Ruichang people, those are "fake" yams, which we call Hongteng and Huaishan. The price is only 1/5-1/4 of Ruichang yam.
what's the difference between Ruichang yam and other yams?
(1) Compared with other common yam, iron stick yam and yam, the content of polysaccharide and glycoprotein is 5% richer. In traditional Chinese medicine, the main function of yam is to nourish the stomach, and the high content of polysaccharide and glycoprotein just plays this role. In traditional Chinese medicine, Ruichang yam is called Jiangnan ginseng, which is the reason.
(2) Unusual yam tastes better than the national yam NO1
If you eat authentic Ruichang yam, you will never choose another yam to eat in the future! Ruichang yam tastes much better than iron bar yam and common yam! National yam taste NO1!
(3) Don't paste after cooking
Authentic Ruichang yam will not paste no matter whether you press it in a pressure cooker or how you cook it. People who have eaten Tiegan yam and other common yams will know that these yams are easy to paste after cooking, and some of them are silky.
