Dairy Hollow House Skillet-Sizzled Cornbread

Why I Love This Recipe
This recipe comes from 'The Cornbread Gospels', a book written by a woman named Crescent Dragonwagon. It is insanely delicious with a heartiness that makes it perfect for serving with a robust chili!
Ingredients You'll Need
Vegetable oil cooking spray
1 cup white all-purpose flour
1 cup yellow cornmeal (finely ground polenta)
1 tbsp baking powder
1/4 tsp baking soda
1/4 tsp salt
1 1/4 cups buttermilk
2 tbsp granulated sugar
1 egg
1/4 cup mild vegetable oil
2 tbsp butter
Directions
Preheat oven to 180 degrees C and spray a 25cm (10″) cast iron skillet with oil and set it aside.
Whisk together the flour, cornmeal, baking powder and salt into one bowl, and stir together the buttermilk and baking soda in a different bowl. Into the buttermilk, then whisk the sugar, egg and oil.
Put the oiled skillet over medium heat, add the butter and heat till it begins to sizzle, making sure to tilt the pan so you coat all the bottom and the sides.
Pour the wet ingredients into the dry and mix together lightly and quickly till just combined. Scrape the batter into the skillet, then pop it into the preheated oven to bake for about 15-20 minutes, or till it’s golden. Once baked, remove from the oven and let it cool for a few minutes before slicing into wedges to serve
