This straight-up variation on the Brandy Smash’s country cousin, the Whiskey Smash, was created to celebrate a friend’s wedding and baptized with said friend’s apartment number. It is pleasing, smooth, rich, and extremely dangerous—as you’ll notice, it’s all booze. Handle with care. (The wedding was a success, even though—or perhaps because—many of the guests got drunk as boiled owls on the 19-B.)

2 ounces straight rye whiskey
1/2 ounce dark Jamaican-style rum
1/2 ounce Grand Marnier
1 sprig mint

Shake with vim and vigor (in this case, you want the bitterness of the mint) and strain through a fine-meshed strainer into a chilled cocktail glass
