This is an authentic German bread recipe found on chefkoch.de. My husband, being German, finds North American bread recipes to "sweet" for sandwiches. This bread is very good and quite healthy. You can use either white flour, whole wheat, ry or whole grain. I prefer using whole grain. If you substitute rye flour you may have to use more yeast and the rising time for the bread will also be longer. Preparation time does not include the length of time for the bread to raise. This a simple recipe and good for beginners.
