Aunt Em's Brown Sugar Doughnuts

Aunt Em is Em McKenney, my Uncle Bud's Aunt

1 1/2 cups brown sugar
1 1/2 tbsp melted oleo (margarine)
2 tsp baking soda
2 eggs
1 tsp cream of tartar
1 tsp salt
1 tsp nutmeg
1 cup sour milk
1 tsp vanilla
flour to roll (probably about 6 cups)

I've never made these particular doughnuts, but all my doughnut recipes are based, in part at least, on Aunt Em's. Call me if you need hints and tips!
