Gin-Lemon CoolerSimple as that. It works best if everything is well-chilled beforehand, so stash that gin and limoncello in your freezer. If you want it a little more sour, feel free to add the juice of a quarter of a lemon, or so. Either way, if your AC breaks some summer evening when it's still 79ºF and humid as a steam room outside, this can help beat the heat, even if just for a little while.
2 oz limoncello
1 oz gin
2 oz seltzer
in a small glass, gently mix the gin and limoncello. Top up with the seltzer.
