A company has introduced a novel potato version of a classic Chinese snack to Beijing supermarkets, as the government tries to stave off a potential food crisis by persuading people of the merits of potatoes as an alternative to rice and wheat. Steamed buns with 30 percent potato content can be found in around 100 supermarkets in the capital, reported Beijing News on Monday. They cost twice as much as traditional steamed buns. Producer Haileda Food Co., Ltd. is currently making one ton of the potato buns each day. If they are well received, Haileda will increase output and expand distribution, the manufacturer said. It also plans to raise the proportion of potato in the buns.
