German rye bread

When I looked through many West Point books, I found that some raw materials were really difficult to find, like rye flour. I have never been clear about the true appearance of this concept. I looked at a package of hotel-specific rye flour given me by a friend. It was written on the package. Yes, you can make steamed buns. I can't imagine what the snacks made with this flour are like and whether they can be used in our West Point works. The difference between rye flour and rye flour was searched online. Finally discovered that they were one family. Rye bread and rye bread, as well as wholemeal bread and germ bread, are the same thing. In order to confuse concepts and play with selling points, merchants create these fancy products. Rye bread and rye bread are common names. Wholemeal bread is the correct name. Some are made black and hard because the proportion of oatmeal flour is large, and the one mixed with wheat flour is softer and lighter. You can't eat pure oatmeal flour. It's like bricks and is very laborious. The reason why there are so many names, In fact, the whole mystery lies in the proportion and production process of oatmeal flour.
