My Mom's Crispy Sugar Cookies
Chill the dough several hours, or even overnight.
You can roll out portions of the dough (keep remaining dough chilled), use cookie cutters to cut out desired shapes, place on parchment lined baking sheets and bake at 325 until they just start to brown at the edges. Cool slightly, then remove to a rack to finish cooling.
You can also just make balls out of the dough, then flatten them with a glass dipped in sugar. You will need to flatten them a LOT, they need to be pretty thin, maybe 1/4 inch.
Sprinkle the cookies with regular or colored sugar before baking, if desired.
