The key here is the quality/quantity of bourbon against the splash size of Roses and Cointreau. The bitters and cherry syrup are critical and cannot be left out. To dry it out, reduce quantity of vermouth.
In an Old Fashioned glass:
-2oz Bourbon, preferably Woodford's Reserve or Jim Beam Black.
-2 tbsp Dry Vermouth
-Splash Roses Lime Juice
-4 dashes, Angostura bitters
-1/4 tsp maraschino cherry syrup
-Orange peel, 3 inch curl
2 oz Rhum Barbancourt
1/2 oz Gosling's Black Seal Rum
1/2 oz Cointreau
1/2 oz Cherry Heering
1/2 oz sweet vermouth
2 dashes Angostura Orange Bitters
Measure all ingredients into glass half of Boston shaker. Shake with ice. Strain into chilled coupe or martini glass. Garnish with a maraschino cherry and a redhead who can tie the stem with her tongue.
