Instructions

1. 1
   Preheat oven to 425°F (220°C). If using a Dutch oven, preheat with 16–18 glowing charcoal briquettes, with 3 times as many on the top as on the bottom.
2. 2
   In a large bowl, mix cornmeal, flour, baking powder, baking soda, and brown sugar, if used.
3. 3
   In another bowl, whisk together the milk, yogurt, egg, and melted butter or olive oil.
4. 4
   Gradually add the dry mixture to the wet mixture and stir until just combined, no longer.
5. 5
   Immediately pour into the greased pan and bake for 15–20 minutes, or until a toothpick inserted in the center comes out clean.
