Ingredients
- 10 large organic, unwaxed lemons (Organic is crucial since you are only using the skins)
- 1 bottle (750 ml) high-proof grain alcohol (such as Everclear 151 or 190 proof) or a high-quality 100-proof vodka
- 3.5 cups water
- 2.5 to 3 cups powdered allulose or erythritol-monk fruit blend (Note: Allulose is highly recommended here as it prevents crystallization when frozen or chilled).
👩🍳 Step-by-Step Instructions
1. Infuse the Peels
- Wash and scrub the lemons thoroughly in warm water to remove any surface residue, then dry them completely.
- Peel the lemons carefully using a sharp vegetable peeler or microplane. Use a light hand—avoid the white pith beneath the yellow skin entirely, as the pith will introduce a permanent bitter taste to your liqueur.
- Combine the lemon peels and the high-proof alcohol in a large, airtight glass jar.
- Steep: Seal the jar tightly and store it in a cool, dark place (like a pantry or cupboard) for at least 14 to 30 days. Shake the jar gently every few days to help extract the essential lemon oils. The liquid will turn a brilliant, deep yellow.
2. Make the Keto Simple Syrup
- In a saucepan over medium heat, combine the water and your chosen sugar-free sweetener.
- Stir constantly until the sweetener is completely dissolved and the liquid is clear. Bring it to a brief simmer, then remove it from the heat.
- Cool completely to room temperature before moving to the next step.
3. Blend, Strain, and Bottle
- Set a fine-mesh strainer lined with a coffee filter or cheesecloth over a large mixing bowl.
- Pour the infused alcohol through the strainer to remove all the lemon peels.
- Combine the vibrant lemon alcohol with your cooled sugar-free simple syrup. You will notice the liquid instantly turns beautifully cloudy—this is the traditional "louche" effect caused by the lemon oils bonding with the water.
- Use a funnel to pour the finished Limoncello into clean glass bottles, like the ones shown in
💡 Serving & Storage Tips
- The Freezer is Key: Store your finished bottles directly in the freezer. Real Limoncello is best served ice-cold in small, chilled digestif glasses. Because of the alcohol content, it won't freeze solid.
