This drink is like the essence of a summer day. It’s made using special lemons that only grow in a certain region of Italy.  In fact, limoncello is protected. This means it can’t be made anywhere else in the world. The lemons are particularly sweet and don’t have the sourness of a regular lemon. When limoncello is made, only the skins are used. They’re steeped in alcohol for at least two days (up to ten) and then added to sugar water. Commercial limoncello goes back over 100 years. The original recipes go back even further than that. Like much of Italian cuisine, the origins of limoncello are shrouded in legend and mystery. One thing is for sure. It has definitely got that timeless quality. Which is what makes this cheesecake extra special.
