1. Prepare the Lemons
Wash and dry the lemons thoroughly. Using a peeler, remove the zest in wide strips. Try to avoid the white pith underneath, as it can add bitterness.
2. Infuse the Alcohol
Place the lemon zest into a clean glass jar and pour the alcohol over it until fully covered. Seal the jar tightly.
Store it in a cool, dark place for 7 to 14 days, gently shaking it every couple of days. The liquid will gradually turn a rich yellow as the oils are extracted.
3. Make the Sugar Syrup
In a saucepan, combine water and sugar and heat gently until fully dissolved. Let the syrup cool completely before using.
4. Combine and Strain
Strain the infused alcohol to remove the zest, then mix it with the cooled sugar syrup. Stir well to combine.
5. Bottle and Rest
Pour the limoncello into clean glass bottles and seal. Let it rest for at least one week before drinking to allow the flavours to balance.
