Shortbread -- Challenge #25: Anything But Turkey

[ewt]

In my house it isn't quite properly Christmas until someone has made shortbread. The recipe is one my mother got off the back of the Canada Corn Starch box, decades ago -- or maybe her mother did.

Equipment needed:
-bowl
-flour sifter or sieve
-I use a thing called a "pastry cutter" (which wikipedia calls a pastry blender, but I was definitely taught cutter because it's for cutting in), but you can mix this with a fork or mixer or something instead
-cookie cutters, or just cut up the dough with a knife (optional)
-rolling pin or wine bottle or something (optional)
-baking tray
-oven
