Espresso Chocolate Shortbread Cookies

I'm not one for coffee, much less espresso, but it was fun to make these nevertheless. I loved the technique of putting the dough into a gallon zip lock bag, rolling it thin and refrigerating. It was fun to slit open the bag and cut the dough into neat squares. Rich thinks these cookies are fabulous and I appreciate his opinion.

And I baked them this morning and took a plate of them to the wonderful mechanics at Elmer's garage who gave me the welcome news that my "check engine" light indicated nothing of any significance. A check engine miracle deserves cookies!
