Make the Batter: Melt 2 tablespoons of butter in a 12 inch cast iron skillet.
Next mix 1 cup extra fine cornmeal, 1 cup medium grind cornmeal, 1 ½ teaspoons baking powder and 1 teaspoon sea salt in a bowl.
Now whisk in 2 eggs, 1 tablespoon of honey and ⅔ cup buttermilk and ⅔ cup water, and the 2 tablespoons of melted butter. Whisk well to combine.
Prepare the Cornbread: Heat a 12 inch cast iron skillet, and add the remaining tablespoon of butter. Once melted and hot, pour in the cornbread batter.
Bake in the oven until firm in the center, about 15-20 minutes. You’ll know it’s done when the top is firm to the touch with a little bit of springiness to it. Allow to rest for 5 minutes then remove from the pan, cut into 16 wedges and serve hot.
