I recently tried the Pink Lemonade cupcake at Sweet bakery in Boston. I know it sounds like it could be hit or miss...but it was in a word: glorious. They also had a couple other new summer flavors including bubble gum. Go out and try one of these gloriously fabulous Pink Lemonade cupcakes as soon as possible.
Quick mention: MARTHA STEWART'S CUPCAKE BOOK NOW OUT!!! I know some people have mixed feelings about Martha post jail but I love her. She can do it all as far as I'm concerned. Anyways, I highly recommend you all go out and buy her new cookbook which is devoted to the most important baked good: cupcakes. This book has 175 cupcake recipes. Amazing. Enjoy!
