Per his website, Brown "strongly recommends" using homemade creamed corn for this recipe to ensure that the cornbread is rich and flavorful with a moist, tender crumb.
Brown starts with his "Better-Than-Granny's" creamed corn recipe which incorporates rosemary and turmeric for a savory herbaceous flavor, but you can use any recipe you prefer.
Cornmeal, low-fat buttermilk, eggs, baking soda, and sugar round out the recipe. Add the creamed corn to the other ingredients and bake at 425 degrees F for 20 minutes.
