I eat oat noodles grew up, should have the right to speak. Avena has a unique regional, Wuchuan County, Inner Mongolia is the most famous, Hebei people also said three "ten miles of oat forty miles of cake (yellow cake), ten miles of buckwheat starvation waist". However, oat noodles to the field has a serious soil and water, difficult to steam, the main reason for the lack of alkaline water in the South, in addition to the acidity of the calcium element in the water also has an impact, but I have not seen first-hand research information. However, there are facts: Shenzhen, and even Japan opened oat noodle halls are from Inner Mongolia to transport water over, and then the problem is solved.
