Use a potato peeler to peel the lemons, making sure to only get the outer peel. The white part will impart a bitter flavor.
Add the lemon peels into a large mason jar.
Pour two cups of Everclear over the lemon peels. Add lemon juice, then seal the jar.
I like to write the date either on the lid, on the bottle, or the calendar. This way I know when to proceed with the next steps.
During the next two weeks to 30 days, store the bottle in a dark place. Shake to agitate every few days, or whenever you remember.
When the appropriate time has elapsed, strain the alcohol into a clean bottle, using cheesecloth soup bags.
Add water and sugar to a small saucepan, and stir. Bring to a boil until the sugar is dissolved and the syrup thickens (about 5 minutes) then cool.
Mix cooled syrup with strained alcohol to combine. Store in the refrigerator or freezer, and drink responsibly!
