Thanksgiving
Culinary historians believe that much of the Thanksgiving meal consisted of seafood, which is often absent from today's menus. Mussels in particular were abundant in New England and could be easily harvested because they clung to rocks along the shoreline. The colonists occasionally served mussels with curds, a dairy product with a similar consistency to cottage cheese. Lobster, bass, clams and oysters might also have been part of the feast.
