Actually, Caine - "shortened" is a baking term that refers to a recipe that is high in fat. And, if you really want to talk about the Shortening bread, the kind mammy's little babies love - it was made with lard, not modern day hydrogenated fluffy shortening. And, similar to a biscuit (Southern US style - not a UK style "cookie") - here is another recipe:
4 cups all purpose flour, sifted
1 cup light brown sugar
2 cups lard, softened
Combine flour and sugar in large mixing bowl and work in shortening with a pastry blender.
Roll dough out to about 1/2 inch thick - cut into 2-3 inch squares - or cut out in rounds with 2-3 inch biscuit cutter.
Bake in a pre-heated 350 degree oven for 20 minutes.
