Anne's cornbread substitute a half cup of polenta (I used whole grain) a half cup of whole wheat flour half tsp of salt half tsp soda 1 tsp baking powder 1 large egg an eighth cup of olive oil 1 tbsp balsamic vinegar 1 cup milk This made a mixture that is wetter than your typical cornbread. I baked it in the oven in a silicone loaf pan at 300 until it was springy to the touch and drawn away from the pan. Very light and crunchy at the same time, and delicious hot with butter or cream cheese.
