Preheat oven to 350 degrees F
Grease a loaf pan (4 1/2 in x 8 1/2 in) with shortening (I like Spectrum) and set aside
In a small bowl, stir together milk and apple cider vinegar
In a medium bowl, stir together the cornmeal, flour, sugar, baking powder, baking soda and salt
Stir in the mild mixture, eggs & oil until just blended. Don't overmix
Pour batter into prepared pan
Bake for about 45 minutes, until golden brown and a toothpick in the center comes out clean. Let cool completely.
To adapt this recipe to corn muffins, adjust the cook time to 20 -25 minutes.
