Limoncello (Italian Lemon Liqueur)

15 Lemons
Two 750 ml 100 proof vodka
4 cup sugar
5 cup water

(allow at least 80 days to cure) Scrub lemons. Peel off zest only, scraping off any bitter white pith. Pour 1 bottle of vodka into a very large jar. Add lemon peel as you go. Store at room temperature in a dark place and let set about 40 days. At this point, make sugar syrup: combine sugar and water in large pot. Bring to boil and cook to thicken about 5 min. Let cool before adding to Limoncello with the other bottle of vodka. Cover and let set 40 days more. Strain into fancy bottles and discard lemon zest.
