Shagbark Seed & Mill Organic Heirloom Corn Polenta is ground on a stone mill to retain its superior flavor and nutrition. Corn is also a good source of vitamin C and manganese. They never use GMO varieties, as is required to be Certified Organic. Polenta, the national staple of Italy, is a great way to enjoy the one-of-a-kind flavor of Ohio-grown Organic Wapsie Valley Corn. It is gluten free and is terrific with braised meats or short ribs. Jazz it up with our DLM parmesan imported from Italy.
