Coconut-Key Lime Squares
It's a new twist on the classic lemon bar: A light, extra-tart Key lime filling on a shortbread crust laced with coconut and white chocolate.
Key limes, so called because they were once cultivated in the Florida Keys, are also known as West Indian, Mexican, or bartender's limes. You'll need anywhere from one-half to two-thirds of a pound, depending on how fresh and juicy they are. If you can't find Key limes, regular limes also make delicious cookies.
