750mLbottle of grain alcoholvodka is an acceptable substitute, but the taste will be a little different
Wash and dry your lemons and then grate or peel them carefully. Be sure not to include any of the pithy white skin beneath the peel, which is bitter.
Place your peels in a sterilized glass jar and top with the grain alcohol. There should be enough liquid to completely cover the peels.
Seal tightly and store in a cool dark place for at least four days. You can leave your mix to steep for up to twenty days however. The longer the peels are left to infuse their flavor into the alcohol, the stronger your limoncello will taste.
Combine the sugar and water in a small pot. Stir over medium heat until the sugar has dissolved completely. Let the syrup cool to room temperature.
Strain the alcohol and discard the peels. The color of the alcohol should be a good dark yellow, and smell very strongly of the lemons.
Pour the simple syrup into the strained alcohol and mix well. Then pour into bottles, seal tightly and let sit in that same dark place for a few days (up to ten) before enjoying.
If your limoncello is too strong for your tastes, try adding a cup of water at a time until it’s diluted to a level you’re comfortable with.
