Limoncello is a traditional Italian liqueur made from lemons. To make homemade limoncello, you will need lemons, vodka, sugar, and water. Start by zesting the lemons and infusing the zest in vodka for a few weeks. Then, make a simple syrup by boiling water and sugar together. Combine the infused vodka with the simple syrup and let it rest for a few more weeks. The result is a sweet and tangy liqueur with a vibrant lemon flavor. Enjoy limoncello on its own as a digestif or use it to make refreshing cocktails like Limoncello Spritz or Lemon Drop Martini.
