Book excerpt: A nightcap is the perfect way to end the night, and author Kara Newman knows just how to make them. This gifty, foil-accented book contains more than 40 cocktail recipes—some to keep the night going, some that will help ease you to sleep, some that can double as dessert, and some that can soothe the stomach after a hearty meal. There are classics like the sweet and creamy Brandy Alexander, new takes on old favorites like the Black Manhattan, which swaps an aperitif for the classic vermouth, and simple new ideas like the Open & Shut, which combines equal parts amaro and cognac for a slow sipper. Whatever kind of night it's been, Nightcap is the perfect way to top it off.
