I love lemons on all food items. The food remains incomplete wothout lemons in it. Hope this recipe helps you.

Ingredients:

One Bottle (750 ml) Everclear (95% alcohol 190 Proof)
One Bottle (750 ml) good but not necessarily premium vodka (40% alcohol 80 Proof)
15 large thick skinned bright yellow lemons (without scars or flaws in the skin if possible.)
750 ml (about 3 cups) filtered tap water or distilled water (not mineral water)
4 cups pure cane white sugar (this will give thin syrup consistency; if you prefer a thicker syrup, experiment with increasing your sugar by 1-2 cups)

Direction:

Dissolve sugar in water and bring to boil over high heat. Boil for 5 minutes.
Set syrup aside to cool. It must be room temp before adding to infusion.
Use a slotted spoon to gently scoop lemon peels from the infusion and discard. To avoid creating small pieces that will make straining more difficult, try not to break peels as you remove them.
Using the larger funnel, the ladle, and #4 coffee filters, slowly strain infusion through filters into large pitcher. This is a messy process. The filters will clog quickly and you will use many of them.
Rinse and dry gallon jar.
Repeat straining process, transferring infusion from pitcher to original gallon jar by straining again through #4 coffee filters.
Return filtered infusion to jar and add COOLED syrup.
Return to cool dry place for 40 days to begin mellowing process that combines alcohol infusion with syrup to create Limoncello.

Steps to be followed on the last (45th day)

Begin filtering Limoncello. Use punch ladle to pour a small amount into a filter-lined funnel held over the small measuring cup.
Fill measuring cup to an even ml level. (100, 200, 300, etc.)
Using smaller funnel and #2 sized filters, filter one last time into individual 100-ml bottles. You have now filtered the liqueur a total of 4 times.
Seal bottles VERY tightly. Remember, if you are using different bottles and are sealing them by corking -- corks breathe. So consider dipping the neck several times in melted wax after corking.
Label and/or tag bottles.
Return to cool dark place for storage
