Limoncello

Zest the lemons and combine the zest and vodka in a non-reactive jug with a cover. Store for two weeks in cool, dark, space. // After two weeks, prepare the syrup by heating a cup of water and a cup of sugar, then cool. Line a funnel with cheesecloth and strain the vodka mixture into a serving bottle. Discard the zest. Add syrup to the bottle and store again for one more week in a cool, dark, space. //At the conclusion of the third week, serve chilled in cordial glass or snifter as a digestive.
