Mom'S Johnny Cake - cooking recipe

Ingredients

1 cup sour milk
1/2 cup sugar
1 teaspoon baking soda
1 teaspoon salt
1 egg
1 tablespoon lard (we always used vegetable shortening)
1 cup flour
1 cup cornmeal

Preparation

Mom's instructions simply say: Mix all ingredients together. Bake at 350 for 20 minutes.
I remember making this in a weird little rectangular pan, which I'm sure we greased. I would estimate this to fit in an 8 or 9 inch square pan, Adjust time accordingly, as the 8 inch will make a litte thicker cake. Bake until a toothpick comes out clean--no longer--so it will stay moist.
