Cornbread with masa harina (instead of corn grits)

Only had masa and wanted cornbread. Found this recipe and it was very delicious.
Here is to provisional cooking, magical substitutions, and the power of corn.

INGREDIENTS

• 1.5 c masa harina

• 1/2 c flour,

• two eggs

• two t of baking powder

• 1 t. salt

• 1 scant T sugar (brown, turbinado, white, honey, whatever)

• 1.5 (approx) c of milk

• 1/2 stick of butter, softened

INSTRUCTIONS

1. Mix dry ingredients.
2. Rub half of butter (2 T) into dry ingr., Put the other half in a cast iron skillet in a 425 oven.
3. Add eggs and enough milk to dry ingr to make a batter (takes more than regular cornmeal bread), around 1.5 c.
4. When butter in skillet is melted, spread out batter and bake until brown around edges and light brown areas on top (about 20 min). Cool out of the pan if you want to keep the bottom crust crisp.
