Rhubarb Shortcake

We are in the depths of rhubarb season. It is not easy finding rhubarb recipes, so I thought I'd share one today.
My mom has made this every year for as long as I can remember.

Preheat oven to 350 degrees F.
Grease an 8" or 9" square pan.

Ingredients:

1 cup sugar
2 cups flour
1 cup sour milk or buttermilk
1 teaspoon baking soda
A pinch of salt
A dash of nutmeg
2 cups rhubarb

Mix sugar and sour milk. Add baking soda and salt. Stir. Add flour and rhubarb and mix well. Pour into prepared pan. Sprinkle with the nutmeg.
Bake for 30 minutes, until it tests done with a toothpick inserted in the middle.
