Traditional Thanksgiving dinner includes turkey, stuffing and mashed potatoes but the First Thanksgiving likely included wildfowl, corn, porridge and venison.
“Wildfowl was there. Corn, in grain form for bread or for porridge, was there. Venison was there,” says Kathleen Wall. “These are absolutes.”
Turkey was not the centerpiece of the meal, as it is today, explains Wall. Though it is possible the colonists and American Indians cooked wild turkey, she suspects that goose or duck was the wildfowl of choice. In her research, she has found that swan and passenger pigeons would have been available as well.
In any case, you'll find that passenger pigeons are unavailable for your menu.
