At the age of 58, with a heart condition threatening to end his life at any moment, celebrated novelist John Steinbeck set out to find America. One of the first things he noticed was that the plural America of his youth, one in which the cadence of life and the words you used were defined by the region you call home, was just as close to fading away as he was.

“It seemed to me that regional speech is in the process of disappearing, not gone but going,” he wrote in his travelogue, Travels with Charley. “Forty years of radio and

20 years of television must have this impact.”

Fast-forward to the modern era, and you now have 90 years of television homogenizing the rich tapestry of American speech, erasing idioms such as New England’s “dropped egg,” the Midwest’s “on pump,” and the South’s “table tapper” (three terms that mean, respectively, a poached egg, something bought on credit, and an amateur preacher in their original parlance.)

But somehow, a handful of subtle regional differences have survived. Depending on which side of the Pennsylvania–New Jersey border you’re on, a group of people might be yinz or youse. Down here, they are y’all, which is, of course, the correct way to address a group. Going to a barbecue means burgers and hot dogs up north and pulled pork down south (which is another point in Southerners’ favor). And it may be helpful to consult a map before ordering an elongated sandwich, which can travel under the aliases sub, hoagie, grinder, hero, or Italian, depending on geography.

Which brings us to one of the deepest gulfs in American regional speech: stuffing vs. dressing.

On a purely superficial level, both words describe the same thing. Everyone has their own recipe (and everyone’s recipe is the best recipe there is), but universally, you take some crumbled bread; toss it with some melted butter, celery, and herbs; and bake it until you have the savory side dish that is all but mandatory at Thanksgiving.

And yet in the North, you’ll call this mouthwatering side dish stuffing. In the South, despite the name also referring to a salad topping, it’s dressing. So why does your position relative to the Mason–Dixon Line matter? Is this one of those simple mistranslations?

Whereas the difference between pop and soda, lightning bugs and fireflies, or sneakers and tennis shoes may come down to simple geography, there is an added twist when it comes to stuffing versus dressing: it’s not just where you are; it’s how you do it.

“I’ve never said stuffing in my life,” Jamie Deen said. As one of the “and sons” in Savannah’s famed Lady and Sons, he speaks from a position of authority. While people across the world first learned about the joys of Southern cooking from his mother Paula’s TV appearances, he learned it at the dinner table.

“Dressing comes in a pan. Stuffing is dressing that is stuffed in the cavity of a bird,” he said. “I think people that do that . . . bless their heart is what we say. As long as you use my mom’s recipe, you can call it what you want.”

Ah, but his mother’s recipe only muddies the waters.

As someone who has extended the appeal of Southern cooking outside our region, Paula Deen offers recipes for both stuffing and dressing on her website. Her “Classic Cornbread Dressing” uses the Southern staple of cornbread as a base with bacon grease an acceptable substitute for butter, while her “Southern Cornbread Stuffing” replaces the cornbread with white bread and saltines.

So clearly the differences between stuffing and dressing run far deeper than just the name. It’s not just about where you’re from. It’s not just about what you do with it. It’s not just about what you make it with. It’s all of these things.

And yet somehow, as with so many things in this great melting pot of America, it’s something we all agree on—or at least agree to disagree. Whether you cook it in a pan or in a bird, with bacon grease or butter, the end result is the same. It’s the side dish that always threatens to steal the spotlight. It’s the great common denominator that brings us all to the table together.

We like to think even Steinbeck would be glad to see one regional idiom standing strong, long after he was gone.
