Preheat grill to medium high heat (425F).
While many cook cornbread in the oven, smoking cornbread is a real treat.
Coat a 10-12 inch cast iron skillet with Crisco and place the skillet on the grill for a few minutes. The fat should begin to smoke.
Mix together the dry and wet ingredients. Set aside and let rise for about 5 minutes.
Pour the batter into the cast-iron skillet and bake on the grill. Allow the cornbread to cook for 45 minutes to one hour. Test with a toothpick for doneness. It should be golden brown and smell slightly smoky.
