Wash and scrub the lemons under hot water, with a vegetable peeler or potato peeler remove the outer peel, remove as much white pith as possible using a paring knife.
In a large glass jar (with a tight closing lid) add the peel and the vodka, close the jar tightly and let sit 12 days in a cool dark place, I find a rarely opened cupboard a good choice. Swirl the ingredients once a day.
After the 12 days, in a medium to large saucepan boil the water and sugar until sugar dissolves, let the mixture cool completely.
Meanwhile strain the vodka/peel mixture through a fine mesh strainer or even cheesecloth. Pour the strained mixture into the cooled sugar and water syrup, and stir well to combine.
Let the Limoncello sit for a day or two at room temperature. Refrigerate or freeze for at least five hours before consuming. Serve straight up or over ice. Enjoy!
Notes
Limoncello can be served straight up or over ice. If you serve it straight up be sure to keep it in the fridge or even in the freezer. I like to place my shot glasses in the freezer too! I like it as cold as possible.In Italy it is served before a meal as an Aperitif or after dinner as a Digestif, always chilled in a shot glass. It also makes the perfect Christmas gift for any and all Lemon lovers.If your bottle of Limoncello hasn't been opened, it can be stored safely in a dark, cool place or fridge. It will keep for up to 3-6 months.If your bottle has been opened, you should refrigerate it or drink it quickly.If it smells bad or tastes bad or even if the taste is too good or too bad it is probably ruined. If there is mold on the cap or around the opening, it is time to throw it out.
