My ex M-I-L had this recipe scribbled on the flyleaf of one of her family cookbooks and no one knew what it was, one year we made it and it was her mom's infamous shortbread cookies. I thought I'd lost the recipe when I divorced, but I found it online (with food processor instructions no less!) and wanted to share. I like bigger cookies so I don't get as many out of the recipe, some friends can get 5 dozen out of theirs. Prep time includes chilling, and it can vary.
