Oh boy are these good!!! I made a half recipe and formed the dough into a log to cut and bake the next day. I cut them 1/2 inch thick and baked for about 14 minutes. They were very fragile right out of the oven so I let them cool completely on the cookie sheet which worked out very well. I also used the Kerry Irish Gold butter and these cookies are so good I won't use anything else for fear of ruining them! Thank you for sharing this incredible recipe.
