Preakness Cocktail

This rainy Friday I chose a 'Preakness Cocktail'.  It didn't sound very interesting but turned out to be one of the best drinks we've had recently. Definitely worth another try.

The recipe (page no. 140 from the Bartender's Guide):

3/4 oz Sweet Vermouth (Noilly Prat)
1 1/2 oz Blended Whiskey (Jim Beam Bourbon, instead)
1 dash Bitters
1/2 teaspoon Benedictine

Stire with ice and strain into cocktail glass.
Add a twist of lemon peel.

Cheers!
