Homemade Limoncello (Limoncello Fatto in Casa) vs Classic American Lemonade

Both drinks start with lemons, but they draw on entirely different parts of the fruit. The limoncello uses only the yellow zest, steeped in high-proof grain alcohol for weeks and then discarded, so its character is aromatic and peel-driven rather than sour. A cooled sugar syrup sweetens it, and months of bottle aging mellow it before it is served ice-cold from the freezer. The lemonade relies instead on freshly squeezed, strained juice, balanced with simple syrup and plenty of cold water for a tart-sweet glass poured over ice and adjusted to taste.
