How to drink Gioia Luisa Limoncello Di Sorrento!

Santa Shelly gave me a box of super dooper goodness for Christmas.  One of my FABULOUS gifts?  A bottle of Giola Luisa Limoncello and's in the freezer and I'm waiting to partook in it!  Yes...I said partook!  GO ME!  

How do YOU drink it?  Have you ever had some?  How did you drink it?  I'm going to add it to fresh lemonade.
