Ingredients:
- 10–12 large, firm unwaxed and preferably organic Lemons
- 750 ml High-Proof Grain Alcohol (190 Proof / 95% ABV preferred)
- 2 ½ cups (500 grams) Granulated Sugar
- 3 cups (700 ml) Filtered or Bottled Water
Instructions:
- Wash and Dry: Thoroughly wash the lemons and dry them completely. Any moisture can cloud the final product.
- Zest Carefully: Using a vegetable peeler or a Microplane, remove only the bright yellow zest. Avoid the bitter white pith beneath the zest. If using a peeler, use a knife to scrape off any visible pith.
- Combine for Infusion: Place the lemon zest into a large, sterilised glass jar. Pour the entire bottle of high-proof alcohol over the zest.
- Seal and Store: Seal the jar tightly. Give it a good shake. Store the jar in a cool, dark place for a minimum of 4 weeks (up to 6 weeks). Shake the jar vigorously once a day for the first week, and then once or twice a week thereafter. The alcohol will turn a brilliant yellow.
- Make the Simple Syrup (After Infusion): After the steeping period, combine the sugar and water in a saucepan. Bring the mixture to a gentle boil, stirring constantly until all the sugar is completely dissolved and the mixture is clear.
- Cool Down: Remove the simple syrup from the heat and allow it to cool completely to room temperature. This is vital; adding hot syrup to the alcohol can negatively affect the flavor.
- Strain the Alcohol: Line a fine mesh sieve with cheesecloth or a clean muslin square. Slowly strain the infused alcohol (the liquore base) into a separate, clean container, discarding the spent lemon peels.
- Combine: Slowly pour the cooled simple syrup into the strained alcohol base. Stir gently to combine thoroughly. The mixture will turn slightly cloudy (the 'ouzo effect'), which is normal.
- Bottle and Rest: Decant the combined Limoncello into the final, sterilised bottles. Seal them tightly.
- The Final Chill: Place the bottles in the freezer (the high alcohol/sugar content prevents freezing solid). Allow the Limoncello to rest and mature in the cold for at least 1–2 weeks before serving.
- Serve: Serve straight from the freezer in small, chilled glasses as a classic digestivo.
