If you guessed chocolate of some kind, you win. The answer is raw cacao nibs. One of my favorite treats.
In other news, we're at Barnes now. I've got a big smile on my face because Tim wore his Captain America shirt to the cafe'. What he didn't know is I smuggled my Cap shirt in. Soon as he went to get a book, I put the same shirt on (over my current shirt).
Tim was not amused. I however, am still smiling.
