Reading this book makes us long for the days when our friends lived closer and had stronger livers. This drink is recommended to be served as a first drink pre-dinner, followed by something stronger before food, almost certainly to be followed with wine at dinner and one or more digestifs.
This drink also inspired us to stock more than just Angoustra bitters. I had vaguely known that there were other types of bitters out there, but the variety was surprising, and there are still so many that I'm eager to try. If you're curious, I recommend the book "Bitters: A Spirited History of a Classic Cure-All, with Cocktails, Recipes, and Formulas" by Brad Parsons as a good introduction to the art of drinking and making all sorts of bitter-like concoctions.
Drink 2: The Astoria
Shake with ice and strain
This was definitely a light drink. The bitters were not really noticeable, though that's partly because we used Hendricks, a very flavorful (and my favorite) gin. We keep our gin in the freezer and chilled the glass, so the drink was very crisp and cold. I've since learned that some distilleries prefer to serve base liquors at room temperature to showcase the flavor, but I'm so far unconvinced.
Overall, I didn't like it very much. If I want an apertif, I'm much happier with a small glass of Lillet Blanc than something that I have to take time to prepare. I am making dinner, after all. In a restaurant, I may order something like this if I had enough courses in front of me that a followup cocktail or two made sense.
Final Verdict
Educational for learning to use orange bitters, but unlikely to make again.
