Mix all dry ingredients, and put Greased (use Crisco or something similar) 10 inch cast iron skillet into 425F oven. Let skillet get hot enough that it starts to smoke a little, and take out of oven. Take a small hand full of cornmeal, and slightly coat bottom of hot skillet as soon as it comes out of oven. Mix oil, buttermilk, and egg into dry ingredients-shouldn't take over 15-20 seconds, and poor into Hot skillet.

Let mixture bake at 425 on medium high rack in oven until light to medium brown on top. Takes about 17-20 min. Take out of oven, turn over on wire rack, and let cool. Best darn cornbread you ever ate. Promise.
