The resulting texture was not quite what I think of as shortbread, and the cookies were a bit salty. Mr Minx said they tasted like Keebler Club crackers, and he was spot on. They definitely needed a bigger bacon flavor. And a grinding of pepper wouldn't be completely out of place.
Because these are refrigerator cookies, I baked only a few and tucked the rest of the dough into the freezer. I may experiment with a roll in a pepper/sugar mixture before baking another batch. Will keep you posted. :)
