1 c. flour
2/3 c. brown sugar
1 tbsp. shortening
1 c. molasses
1 egg, well beaten
3/4 c. hot water
1 tsp. baking soda
1 tsp. vanilla

I prefer Grandma's unsulphured molasses.

Mix flour, sugar and shortening. Set aside 1/2 cup of the crumbs. Pour hot water over soda and add molasses, well-beaten egg, vanilla and crumbs. Pour into unbaked pie crust and sprinkle the 1/2 cup of crumbs on top of pie. Bake at 425 degrees for 10 minutes, then reduce to 350 degrees for 45 minutes.
