A German ligature that originally stood for 'sz', but can be transliterated as 'ss'. It is never found in Swiss German. It looks like a B, but sounds like an S. Compare to the boring language known as English, which only has the ligatures Ã and Å, which are rarely used.
The only other flour used in traditional pumpernickel is wheat flour, which is used as an ingredient in the sourdough starter, a pre-fermented flour, water and yeast mixture that combines with the rye flour to hold the bread together.
Pumpernickel is a form of German bread, referenced at least as far back as the 1450s. It is characterized by its dark color, very thin crust, and rye flavor.The traditional method for producing this bread is to combine course and fine rye flour with a sourdough starter and sometimes yeast.umpernickel has no yeast or source dough content. Yeast, sourdough and rye or wheat/rye mixes create the common german breads called grey bread or black bread and these breads are baked, not steamed.
