Preheat the oven to 350˚F. Add 1 tbsp of unsalted butter to a cast iron skillet. Put the skillet in the oven and allow to heat until very hot, 6 to 8 minutes.
In a bowl combine cornmeal, flour, baking soda, baking powder, chives, corn kernels, jalapenos and salt.
In another bowl combine the wet ingredients: milk, buttermilk, lightly beaten eggs. Then add molasses and remaining melted butter. Mix well.
Make a well in the center of the dry ingredients and pour in the wet ingredients. Fold to combine.
Carefully remove the hot skillet from the oven and pour in the batter.
Bake for 25 min. or until the cornbread is golden.
