A traditional Thanksgiving dinner usually consists of (at the very least) a turkey with stuffing, mashed potatoes, cranberry sauce and pumpkin pie, however, as Guardian Food points out, the very first Thanksgiving feast in 1621 looked a lot different.
The only written account says that they ate five deer and some birds, probably a swan or a duck. Wild turkeys were harder to hunt down, but shellfish were easy to find, so they probably made it into the feast. …Cranberries were around, but sugar wasn’t. …As for potatoes, they were mostly still in South America. Stuffing made kind of an appearance, but it was pretty basic.
