Pumpernickel

Pumpernickel (english: ; german: [ˈpʊmpɐˌnɪkl̩]) is a typically heavy, slightly sweet rye bread traditionally made with sourdough starter and coarsely ground rye. it is sometimes made with a combination of rye flour and whole rye grains ("rye berries"). at one time it was traditional peasant fare, but largely during the 20th century various forms became popular through delicatessens and supermarkets. present-day european and north american pumpernickel differ in several characteristics, including the use of additional leaveners. the north american version may have coloring and flavoring agents, added wheat flour, a higher baking temperature, and a dramatically shortened baking time.
