Other forms: pumpernickels
The dark, somewhat heavy bread you can buy in a bakery or deli is called pumpernickel. If you're bored with the sesame bagel, try ordering a pumpernickel instead.
Pumpernickel is a hearty, slightly sweet bread that's made with whole-grain rye flour and traditionally has a dark brown color. While American pumpernickel gets its color from molasses or coffee, traditional German pumpernickel is baked or steamed for a very long time at a low temperature to get its brown shade and sweet flavor. In German, pumpernickel was originally a derogatory name for a simpleton — and the bread itself was once called krankbrot, or "sick bread." Historians think that's because a dark bread was supposedly developed to feed people who were sick during a famine in the 1400s.
