Mix flour, sugar and shortening. Blend with a pastry knife until crumbly, resembling
oatmeal. Place the mixture in a greased pie pan and spread evenly on the bottom
and up the sides, being careful not to compress the mix.
Blend molasses, baking soda and boiling water. Carefully pour over the crumbs.
Bake for 45 minutes. The sides will be slightly puffy when done.
