1. Set a 12-inch cast-iron skillet in the oven and preheat the oven to 375°. In a large bowl, whisk together the eggs and sugar until frothy, 1 to 2 minutes. Whisk in the buttermilk, sour cream and honey.

2. In another medium bowl, whisk together the flour, cornmeal, baking powder, baking soda, salt and cayenne. Use a wooden spoon to stir the flour-cornmeal mixture into the sour cream-buttermilk mixture. Stir in the melted butter and mix until well combined.

3. Remove the hot cast-iron skillet from the oven and add the remaining 2 tablespoons of butter, swirling the pan to evenly disperse the butter. Pour in the batter, using the back of the spoon to spread it into an even layer. Bake until a toothpick inserted into the center of the cornbread comes out clean, about 25 minutes. Remove from the oven and cool slightly before slicing and serving.
