Despite the popularity of the iconic turkey, historians say that no turkeys were served at the first Thanksgiving! Instead animals like deer or venison, ducks, geese, oysters, lobster, eel and fish were on the menu. They likely did consume pumpkins, but certainly no pumpkin pies. BLASPHEMY. And even crazier is that they also didn’t eat mashed potatoes or cranberry relish. The thought of having no mashed potatoes for Thanksgiving makes me physically ill.
