As the name suggests, the authentic recipe is just rye whiskey and dry vermouth with a dash of orange bitters. This should perhaps be renamed "Rye & Bone...
Used a quality 90 proof rye, but it got lost in the orange bitters and expression. It is DRY. Will definitely try with my 100 proof rye next time and follow Simon's recommendations.
It's very elegant according to our host's recipe. But we look forward to tinkering with it. To our taste it is more of an Old Fashioned than a Martini but we can see why people might want to go either way.
