Delicious Gingerbread

Ingredients

Directions

Melt the butter with the molasses and sugar in a saucepan.
While warm, add the sour milk, baking soda, and flour.
Mix until smooth. Optionally, add 1 tablespoon of vinegar for extra flavor.
Pour the batter into long pie tins.
Do not overfill the flour cups to avoid a thick batter.
