Easy! A delicious cold after dinner liqueur.
Put the date on the bottle. Put the jar in a cool, dry place for one week. Once a day, shake the contents well to remix everything. You'll notice the color of the liquid changing to yellow and the color of the lemon peels fading.
One week later, dissolve the sugar completely in water by heating it on the stove. Then cool the sugar-water mixture to room temperature. Strain the lemon peels out of the alcohol and then mix the alcohol with the sugar-water. Usually the color of the alcohol changes from clear yellow to cloudy yellow when it's combined with the sugar-water. Pour the mixture into bottles which can be sealed tightly and store them in the freezer. If the limoncello is kept "frozen" until serving, it becomes thick and syrupy.
