Actually this is not a specific recipe.  Just about everyone in Italy that makes Limoncello has their own special recipe that is usually a concoction of special-grown lemons, water, sugar and gruppa (or vodka).

To celebrate The Olive Oil King and The Principessa, Limoncello was available to make a toast to Kate and Alessandro and to Italy.  I think we all agreed, this could definitely be an adult lemonade.
