Limoncello Recipe

Prepare lemons

Wash the lemons thoroughly with hot water and a vegetable brush to remove any residues. Pat dry. Using a vegetable peeler or sharp paring knife, remove the yellow zest only, avoiding the white pith as much as possible. You should end up with long strips or peels from all 12 lemons (about 1.5–2 cups of packed zest).

Combine zest and spirit

Place all lemon zest into a very clean, large glass jar or multiple jars (1.5–2 L capacity). Pour the 1.5 liters of high-proof vodka (or other neutral spirit) over the zest, ensuring the peels are fully submerged. Seal the jar tightly.

Infuse

Store the jar in a cool, dark place at room temperature. Let the zest steep for 7–14 days, shaking the jar gently once a day to agitate the peels. Check color and aroma: the spirit should turn bright yellow and smell strongly of lemon. Taste after 7 days; if you want a stronger lemon flavor, continue up to 14 days. Avoid over-infusing longer than 14–21 days to prevent undue bitterness from pith compounds.

Make syrup

About 24 hours before you plan to finish the limoncello (or right after removing infusion), combine 3 cups granulated sugar and 2 cups water in a medium saucepan. Heat over medium heat, stirring, until the sugar is completely dissolved and the syrup is clear. Do not boil vigorously; a gentle simmer is fine. Remove from heat and let the syrup cool to room temperature. For a lighter sugar level, you can use 2 cups sugar to 2 cups water (adjusts final sweetness and ABV).

Strain infused spirit

When infusion is ready, strain the lemon-infused spirit through a fine-mesh sieve lined with cheesecloth or a coffee filter into a large pitcher or bowl to remove zest and any small particles. Press gently on the peels to extract the infused spirit but avoid forcing pithy, bitter compounds. Discard the used peels.

Combine syrup and infusion

Slowly add the cooled simple syrup to the strained lemon spirit, stirring gently. Taste and adjust: if too strong or too boozy, add more cooled syrup or a little water; if too sweet, add a small amount of un-sweetened infused spirit (reserve some before adding all syrup) or dilute with water. The typical final ABV should be in the 25–30% range depending on spirit and syrup ratio.

Rest and clarify

Once combined, let the limoncello rest for 1–7 days in a cool, dark place to allow flavors to marry and any remaining particulates to settle. If you notice cloudiness, you can fine-filter through coffee filters or use a paper filter in a funnel until clear.

Bottle and chill

Using a funnel, pour the finished limoncello into sterilized bottles, seal tightly, and label with the date. Refrigerate or freeze before serving. Serve ice-cold in chilled liqueur glasses. Keeps for several months refrigerated; flavor will mellow over time.

Optional garnish

When serving, you may float a little fresh lemon zest (about 1 tbsp distributed across servings) or a thin lemon wheel for aroma. Discard garnish before long-term storage.
