Ingredients:
1 ¼ cups buttermilk. I have not tried this yet with substituting vinegar + milk, but I will when I run out my current bottle of buttermilk.
1 ½ cups Quaker corn meal.
½ cup King Arthur all-purpose flour
1 ½ teaspoons baking powder. I’ve had trouble w/ generic store brands; name brand seems to work better.
