My attempted Irish Car Bomb cookie kinda blew up on me. Well, actually, maybe it's more accurate to say that they were duds. Or that these bombs bombed. In other words, these cookies were definitely not bring-in-able.
These guys didn't spread out when baking; had a dry, cakey texture; and--perhaps most surprising--were hollow.
Here's what I learned from the postmortem: I inadvertently used twice as many currants as I had planned. I forgot to use McCann's Irish oatmeal. The Guinness was so sudsy that I probably didn't need to include baking soda...or I could have used about half as much. D'oh!
Back to the drawing board. I guess practice really does make perfect.
