Habanero Cornbread

1-1/2 cups yellow cornmeal 1/2 cup flour 1/2 teaspoon baking soda 1 teaspoon baking powder 1 teaspoon salt 1 teaspoon sugar 1 cup canned cream style corn 1 medium onion, finely chopped 1 or more habaneros, finely chopped 1 cup grated cheddar cheese 1/4 cup corn oil 2 eggs, slightly beaten 1 cup buttermilk This recipe is definitely for the serious chilehead!  This is the best cornbread ever. For the faint of palate,  you can substitute jalapenos for the habaneros and  still have a very tasty cornbread. Preheat oven to 450 degrees.  Place greated cast iron skillet in the oven to heat.  Combine dry ingredients.   Combine remaining ingredients; add to  dry ingredients and fold in. Pour the batter into the heated skillet and bake  for about 20 minutes or until golden brown.
