What Was Not on the Menu
Surprisingly, the following foods, all considered staples of the modern Thanksgiving meal, didn't appear on the pilgrims's first feast table:
Ham: There is no evidence that the colonists had butchered a pig by this time, though they had brought pigs with them from England.
Sweet Potatoes/Potatoes: These were not common.
Corn on the Cob: Corn was kept dried out at this time of year.
Cranberry Sauce: The colonists had cranberries but no sugar at this time.
Pumpkin Pie: It's not a recipe that exists at this point, though the pilgrims had recipes for stewed pumpkin.
Chicken/Eggs: We know that the colonists brought hens with them from England, but it's unknown how many they had left at this point or whether the hens were still laying.
Milk: No cows had been aboard the Mayflower, though it's possible that the colonists used goat milk to make cheese.
