Prepare the Tools: Preheat oven to 400 degrees F. Place two tablespoons butter in cast iron skillet and place pan in oven to melt.
6 tablespoons unsalted butter
Make the Batter: Whisk together cornmeal, flour, baking powder, baking soda, sea salt, cinnamon, ginger, and nutmeg. Set aside.
1 cup flour, 1 cup cornmeal, 1 tablespoon baking powder, 1 teaspoon baking soda, 1 teaspoon fine sea salt, ½ teaspoon ground cinnamon, ¼ teaspoon ground nutmeg, ¼ teaspoon ground ginger
In another bowl, beat eggs then mix in sweet potato puree, brown sugar, and melted butter until uniform. Stir in buttermilk.
2 eggs, 2 cups sweet potato puree, ⅓ cup brown sugar, 1 cup buttermilk
Bake the Cornbread: Fold wet mixture into dry mixture and stir until just combined. Carefully pour batter into skillet with melted butter (this helps create crispy edges!) then place skillet back in oven to bake for 25-30 minutes or until golden brown and a toothpick inserted into the center of the cornbread comes out clean.
Finish and Serve: Meanwhile, melt butter for the glaze then mix vigorously with honey and salt. Brush honey butter mixture over top of baked cornbread before serving.
¼ cup unsalted butter, 3 tablespoons honey, 1 pinch fine sea salt
