While similar to the Manhattan, it was based on Scotch instead of Rye or Canadian Whiskey. There were several versions of the Rob Roy circulating around in the Fifties. There was a sweet, a Dry, and the "Perfect" Rob Roy recipes. The difference being the type of Vermouth that was used.
I'm tending toward a dry version that is being made with Plantation Trinidad 2000 Rum. The notes of Scotch that a apparent in the Plantation rum makes for a great marriage into the cocktail's original recipe. There is an inherent sweetness to the rum that lends its self to the dryer versions of the original cocktail.

Give this one a try, I think you will find it very satisfying. ;o)
