They Held Their Noses, and Ate

NO contemporary American holiday is as deeply steeped in culinary tradition as Thanksgiving. Not only is the day centered on a feast, but it’s also a feast with a narrowly proscribed list of foods - usually some combination of turkey, corn, cranberries, squash and pumpkin pie. Decorated with these dishes, the Thanksgiving table has become a secular altar upon which we worship America’s pioneering character, a place to show reverence for the rugged Pilgrims who came to Plymouth in peace, sat with the Indians as equals and indulged in the New World’s cornucopia with gusto.
But you might call this comfort food for a comfort myth.
The native American food that the Pilgrims supposedly enjoyed would have offended the palate of any self-respecting English colonist - the colonial minister Charles Woodmason called it “exceedingly filthy and most execrable.” Our comfort food, in short, was the bane of the settlers’ culinary existence.
Understanding this paradox requires acknowledging that there’s no evidence to support the holiday’s early association with food - much less foods native to North America. Thanksgiving celebrations occurred irregularly at best after 1621 (the year of the supposed first Thanksgiving) and colonists observed them as strictly religious events (conceivably by fasting).
It wasn’t until the mid-19th century that domestic writers began to play down Thanksgiving’s religious emphasis and invest the holiday with familiar culinary values. Sarah Josepha Hale and her fellow Martha Stewarts of the day implored families to “sit down together at the feast of fat things” and raise a toast to the Thanksgiving holiday. When Abraham Lincoln declared Thanksgiving a national holiday in 1863, the cornucopia-inspired myth was, as a result of these literary efforts, in full bloom.
This secular transition laid the foundation for families to adopt what had become familiar American foods as the holiday’s bountiful centerpiece. Popular as they might have been in 19th-century America, however, the earthy victuals that Thanksgiving revisionists arranged on the Pilgrims’ fictional table were foods that Pilgrims and their descendants would have rather avoided.
The reason is fairly simple. Hale and her fellow writers seem to have forgotten that their Puritan forebears migrated to New England with strict notions about food production and preparation. Proper notions of English husbandry generally demanded that flesh be domesticated, grain neatly planted and fruit and vegetables cultivated in gardens and orchards.
Given these expectations, English migrants recoiled upon discovering that the native inhabitants hunted their game, grew their grain haphazardly and foraged for fruit and vegetables. Squash, corn, turkey and ripe cranberries might have tasted perfectly fine to the English settlers. But that was beside the point. What really mattered was that the English deemed the native manner of acquiring these goods nothing short of barbaric. Indeed, the colonists saw it as the essence of savagery.
From the colonists’ perspective, Native Americans grew crops in an entirely corrupt manner. They typically prepared fields by setting fire to the underbrush and girdling surrounding trees. Afterward, they planted corn, gourds and beans willy-nilly across charred ground, possibly throwing in fish as fertilizer. To the Indian women who tended the plants with clamshell hoes, the ecological brilliance of this arrangement was abundantly clear: the cornstalks stretched into sturdy poles for the beans to climb upon, the corn leaves fanned out to provide squash with shade, and the beans enriched the soil with extra nitrogen. But the English, blinded by tradition, never got it - they just looked on in horror.
Where were the fences? The neat rows of cross-sectioned grain? The plows? Where were the carts of dung? The team of oxen? The yokes? Why were perfectly good trees left to rot? Why not burn them to power a fireplace? And those fish! Why not salt them down and export them to Europe for a tidy profit? What was wrong with these people? The collective English answer - “everything” - honed the colonists’ distaste for foods, especially corn and squash, that they quickly judged best for farm animals.
A similar culinary misunderstanding developed over meat. To be sure, the English frequently hunted for their meals. But hunting was preferably a sport. When the English farmer chased game to feed his family, he did so with pangs of shame. To resort to the hunt was, after all, indicative of agricultural failure, poor planning and laziness.
Thus the colonists reacted with extreme disapproval when they saw Indian men adorned with paint disappearing into the woods for weeks at a time to track down protein. Making the scene even more primitive was that the women who stayed behind spent their time tending crops, lugging water from the creek, and toiling away at odd jobs that the English valiantly considered men’s work. The elk, bear, raccoon, possum and indeed the wild turkeys that the men hauled back to the village were, for all these reasons, tainted goods reflective of multiple agricultural perversions.
They were also, much to the settlers’ chagrin, entirely unavoidable. The methods that colonists condemned as agriculturally backwards - and the food these methods produced - became necessary to their survival. No matter how hard they tried, no matter how carefully they tended their crops and repaired their fences and fattened their cattle and furrowed their fields, colonial Americans failed to replicate European husbandry practices. Geography alone wouldn’t allow it.
The adaptation of Indian agricultural techniques not only sent colonists deep into the woods galloping after game and grubbing corn from unbound, ashen fields, it also provoked severe cultural insecurity. This insecurity turned to conspicuous dread when the colonists were mocked by their metropolitan cousins as living, in the words of one haughty Englishman, “in a state of ignorance and barbarism, not much superior to those of the native Indians.”
This hurt. And under the circumstances no status-minded English colonist would have possibly highlighted his adherence to native American victuals - even if the early Thanksgiving holiday had been a genuine culinary event. Indeed, it wasn’t until after the Revolution, when the new nation was seeking ways to differentiate itself from the Old World, that these foods became celebrated as a reflection of emerging ideals like simplicity, manifest destiny and rugged individualism.
Today, of course, we proudly evoke this native American heritage by crowding the table with turkey, corn, stuffing, cranberry sauce and pumpkin pie as if they had always been there. That they weren’t shouldn’t be a cause for chagrin, but a reminder that Americans have survived in some measure because we are endlessly adaptable and capable of overcoming our deepest prejudices - even if the Pilgrims wouldn’t have approved.
