Limoncello

Limoncello is made with the lemons hanging in little cheesecloth hammocks, suspended above the high proof spirit, rather than peeling the lemons and immersing said peels in the spirit. Because alcohol
volatilizes pretty easily at room temperature, the alcohol vapors are macerating the lemon peel. Because it’s doing it from the outside in, you’re just getting the whole zesty flavors, with none of the bitter pith. This is actually a very old Sicilian technique for making citrus liqueurs. Fresh lemons ensure a crisp taste.
