Rösle Boston Shaker

You know all those cocktail shakers we've told you about? Yeah, you shouldn't have bought any of those. Our bad. The Rösle Boston Shaker ($47) is our new favorite. Instead of the sometimes-leaky shakers that you can't see inside or measure easily, this one comes with a glass tumbler that's marked with measurements, letting you free-pour your ingredients like a pro bartender.
