Ordering a Dry Martini is a lot like ordering a steak. What cut of meat? How well done? And with what sauce? The analogy translates to Martini garnishes...
I don’t know what it’s called, but my “bone dry” Gibson preferred ratio is 8:1. 2oz. Gin .25oz. Vermouth. I’m also using vermouth-brined onions which leach out a little bit of that flavor.
