Cornbread

Motivation
I like to buy blue cornmeal so I can make purple cornbread (obviously).  Recently the cornmeal bag has changed the cornbread recipe from the awesome bare-bones recipe to a fancy-smancy recipe with sugar and such.  My stance is that cornbread shouldn't have sugar in it because you're going to slather it with butter and honey eventually anyway.

Ingredients
1 cup Cornmeal (blue preferably)
1/2 cup Flour
1 tsp Salt
1/8 tsp Baking Soda
1 cup Milk

Method
Place cast iron skillet in oven and preheat to 425 degrees F.  Whisk all the dry ingredients together.  When oven is preheated add milk to dry ingredients and mix until incorporated.  Spread batter into hot cast iron skillet and bake for 20-25 minutes.  Serve hot.
