1/2 cup sugar
1/2 cup molasses
1/2 cup shortening(scant)
3/4 cup sour milk
2 1/2 cups flour
1 teaspoon soda
Spices (see note)
no method but here is a general suggestion:
350 degrees. Grease and lightly flour a metal pan.
Whisk dry ingredients(except sugar) and spices in a large bowl.
Mix milk and egg.
Add about 1/2 of the milk mixture and beat until smooth. Add remaining milk mixture in two stages; beat until batter is just smooth.
Add the sugar; beat until just incorporated, about 30 seconds.
Pour batter into cake pan.
Bake until a cake tester or toothpick inserted into the cake's center comes out clean.
Set pan on a wire rack; let cool for 5 minutes.
Run a knife around the pan perimeter and turn cake onto rack. Let cool.
Here is a typical spice blend, but I think that the intended is 1/2 teaspoon of each:
2 teaspoons ground ginger
1 teaspoon ground cinnamon
1/2 teaspoon ground nutmeg
1/2 teaspoon ground allspice
1/2 teaspoon ground cloves
