The Jiffy mix cornbread even just mixed up is really good IME but probably not in the opinion of Southerners who won't let a spoonful of sugar adulterate (ITO) a piece of cornbread!! But Maria's recipe is really good--I bake it in an 8X8 or 9X9 which is about the same size as her dimension.
What appetizer would cornbread be in? Interesting.
