We've been having a bit of fun learning more about craft cocktails. We recently purchased this book, along with the sphere ice cube molds, and the king cube molds. We already own a cocktail shaker, but I posted one that's popular now - and it's made by the same fellas who wrote the book. The book has some great cocktail recipes, and the ice cube molds are super easy (and fun!) to make - and they make such a difference by not watering down your drink as fast as regular ice cubes. I definitely recommend these as a great gift ideas.
