I've been eying this book since I heard about its upcoming release. For me, a cocktail book with a French slant is a hugely appealling. I flipped through it at my local bookstore and was compelled to buy it when I saw a recipe calling for Byrrh, along with a few re-interpreted classics. The recipes are not overly complex and generally don't call for esoteric ingredients. If you have Sam Ross' Bartender's Choice app, it's in the same vein but with a definite French (and international) touch, with recipes calling for things like Suze, Armagnac or Japanese whisky.
Measurements are given in milliliters and ounces, and were probably conceived in metric so they can be a bit unusual sometimes, but this is not a big deal at all. Each recipe is provided with a little background about its creation or general concept, which I always find the most interesting part of these types of books.
The first thing I mixed was the Byrrh cocktail of course. It had quite a few other ingredients, but luckily I had everything already on hand.
Handsome Jack (Chris Tanner) with Rittenhouse straight rye, Pierre Ferrand 1840, Aperol, Byrrh, green Chartreuse, maple syrup, Angostura and Peychaud's bitters.
As indicated in the notes, it is slightly on the sweet side but it has a slight bitterness that compensates for that (from the Byrrh and Aperol). The flavor is deep and complex. There is almost like a chestnut note with the maple syrup and cognac, and a nice kick from the rye. A very good fall/winter drink.
