This cocktail is a variation on various whiskey-based cocktails which are part of my standard drinking menu. The Manhattan is the most basic, then it spins out to variations like the Compass Rose or the Vieux Carre.
I tinkered with the Boulevardier a little, and this is one totally bomb-ass result:
The Brookline Boulevardier
Chill a cocktail glass with crushed ice.
In a mixing glass, over ice, combine:
1 oz Dad's Hat Cask Strength Single Barrel Rye
1 oz Jim Beam Signature Craft 12yr Bourbon
1/2 oz Carpano Antica Vermouth
1/2 oz Aperol
2 dashes No. 11 Orange Bitters
Stir until well-chilled, at least 30 seconds. Empty your cocktail glass of crushed ice. Strain the cocktail into the glass over a slice of blood orange for garnish.
Substitute ingredients as necessary or get over to my place and I'll mix you one.
