Grated Sweet Potato Casserole

This is old-fashioned and rarely used, but is especially delicious during holidays with turkey and ham.

1 1/2 cups granulated sugar
1/2 cup milk
3 cups grated raw sweet potatoes
2 eggs
1/2 cup (1 stick) margarine
3/4 cup buttermilk
1/8 teaspoon baking soda
1/2 cup pecans
1/2 teaspoon cinnamon

Mix sugar and milk in large bowl; add potatoes. Beat eggs; add butter. Combine two mixtures. Add remaining ingredients and mix. Pour into 2-quart casserole and bake for 1 hour at 450 degrees F.
