Marsh Hen Mill
A Day with Marsh Hen Mill’s Greg Johnsman
We try not to take for granted that we are based in one of the most iconic food cities in the country. The Lowcountry in particular is known for its abundance. Fresh shrimp, oysters, and crab. Fragrant fruits and vegetables that shift with the seasons. Bright red strawberries in the spring and juicy red tomatoes in the summer. And, of course, the foundation of rice that influenced so much of early South Carolina’s history.
As a cast iron company, and a cookware company more broadly, we’re obsessed with food. Restaurants, culinary traditions, what’s in season, and knowing the right people help us make the most of living in such a flavorful locale. When we connected with Greg Johnsman of Marsh Hen Mill, we thought we were simply learning more about the grits, rice, peas, and corn he produces. What we found was much more.
Greg is a family farmer whose values align seamlessly with ours. Authenticity, tradition, and quality are not just words you will find on the Marsh Hen Mill website; they are embedded in everything he does. He honors tradition, works with intention, and is uncompromising when it comes to quality.
We first sat down with Greg at his restaurant Miller’s All Day in downtown Charleston. A beloved brunch spot, the space designed in a mid-century modern style as a tribute to his grandmother and named for someone who mills all day. Over a skillet-sized cinnamon roll and a perfect cup of coffee, Greg showed us a photo of his personal cast iron collection. We thought we were cast iron enthusiasts until we met Greg.
His appreciation for cast iron goes far beyond how it cooks. It reflects the same values he brings to his work. Cast iron is durable, reliable, and built to last. It has been around for centuries and continues to provide for those who use it well.
We later visited Greg’s home to see his collection in person and were blown away. Vintage and modern pieces filled the space, purchased over decades or gifted by friends who understand his passion. Eries, Wagners, Griswolds, left-handed skillets, right-handed skillets, and even the occasional knockoff. Corn pans, muffin pans, enameled pieces, chromed finishes, and more.
We spent hours talking and learning while Greg made us cornbreads- yes, plural-using Marsh Hen’s grains. Jimmy Red corn, Sea Island Blue, Oaxacan Green. Each one grown, milled, and cared for by Greg and his family on Edisto Island. It left us with a deep appreciation not only for the product, but for the energy and intention behind it.
When Greg invited us to see the mill, we did not hesitate. We followed him and his dog, Mrs. Beatrice Brown, down the moss-lined roads of Wadmalaw Island and onto Edisto.
The mill, once a tomato farm, carries the same spirit as everything Greg touches. Stickers from friends and visitors cover the doors.
Inside the mill room, we watched the process up close. Corn moved from kernel to grits to meal through “Dirty Gerty,” the mill that fills the room with dust and noise. Watching fuchsia-colored “unicorn” kernels being poured, pressed, and milled gave us a completely new appreciation for the work. It combines physics with skill and attention to detail, forcing you to slow down and focus.
This is the kind of work that takes time, but it produces something that tastes like tradition. Something grounded in quality. We wanted to share Greg and Marsh Hen Mill’s story because it represents the kind of craft we believe in. Honest work, done with intention, resulting in something beautifully authentic.
