Wash the lemons with a vegetable brush and hot water to remove any reside of pesticides or wax; pat the lemons dry. Using a potato peeler, take all the lemon rinds off of the lemons so there is no white pith on the peel. Place the rind-peelings in a large container with the Everclear alcohol. Cover the container and let it sit for seven days.
On the eight day, strain the the peels from alcohol; discard peels.
In a large saucepan, make a Basic Simple Syrup by combining the water and sugar; let it simmer "fast" for 15 minutes. Let simple syrup cool to room temperature. Add to alcohol.
You are now finished and can drink it right away.
Makes about 2 1/2 liters.
* Choose thick-skinned lemons because they are easier to zest. The lemons must be yellow and not tinted with green.
