Affinity
Scotch Whisky - 2 oz
Sweet Vermouth - 1/2 oz
Dry Vermouth - 1/2 oz

Stir this drink with ice and strain into a chilled martini glass.
Let&amp;#8217;s start from the beginning, most of us are familiar with the Manhattan cocktail, it&amp;#8217;s made with American whiskey (usually rye or bourbon) and sweet vermouth with a dash or two of bitters. A Rob Roy is a variation of the Manhattan that uses Scotch instead. And the Affinity is nothing more than a perfect Rob Roy. The term &amp;#8220;perfect&amp;#8221; does not refer to the quality of the drink, but rather describes the sweetness or dryness of it, in another word: medium. A medium cocktail always mean that both sweet and dry vermouths are used, often 50:50.
And this is the difference between the Affinity cocktail and a Rob Roy cocktail. Most bartenders nowadays would get these two mixed up, and thinking they are the same, but in fact Affinity is a little drier.
I prefer to garnish this drink with a lemon twist, release some citrus oil on the surface. According to an old rule: cherry for the sweet, lemon for the dry.
