  • "What made it worse, being English, they did not want to eat unfamiliar food.... The waters were so rich in lobsters that they were literally crawling out of the sea and piling up inhospitably on the beaches. But the Pilgrims, and most people until this century, did not want to eat these huge, clacking, speckled sea monsters. Apparently in desperation, they were eventually reduced to eating lobster. In 1622, Bradford reported with shame that conditions were so bad for the settlers of New England that the only 'dish they could presente sic their friends with was a lobster.'"
