Where I can find the real deal pumpernickel or dark rye bread, the kind that makes good deli sandwiches? I suppose Karl's has both, but I'm hoping for a place in the immediate Boston area.
As an aside, I looked up the origin of pumpernickel and found the below from straightdope.com. Look out!
The true origin of "pumpernickel" is nearly as strange, if somewhat less savory. "Pumpern" was a New High German word similar in meaning to the English "fart" (so chosen because, like the word "achoo," it imitated the sound it described), and "Nickel" was a form of the name Nicholas, an appellation commonly associated with a goblin or devil (e.g., "Old Nick" is a familiar name for Satan). Hence, pumpernickel is the "devil's fart," allegedly a reference to the bread's indigestible qualities and hence the effect it produced on those who consumed it.
