I couldn't help myself. With the scrumptious results of the shortbread earlier this week, I had to try another of Dorie's shortbread recipes. And what better one than a recipe with two daily necessities?
Coffee and chocolate.
The very minor addition was a pinch of salt. After mixing up the batter, I tasted it and thought, "Oooh, flat." I don't know if that was an intentional omission, but a little salt is always needed in shortbread.
