Add 45ml Scotch whisky, 30ml sweet vermouth, and 2 dashes orange bitters to a mixing glass.
Fill the mixing glass with ice and stir for 20–25 seconds until well chilled and properly diluted.
Strain into a chilled cocktail glass.
Garnish with a cocktail olive and serve immediately.
The vermouth ratio here is intentionally more generous than a Rob Roy - dial it back to 20ml if you prefer a drier, more Scotch-dominant build, or lean into a blended Scotch for approachability versus an Islay single malt for full smoke impact.
