Here's yet another Irish Cocktail. This is also called an Irish Manhattan and Paddy Cocktail, but I feel Paddy Wagon is the best title.
aka Irish Manhattan
2 oz Irish Whiskey
¾ oz dry vermouth
2-3 dashes Angostura bitters
Stir the liquid ingredients in mixing glass with ice. Strain into chilled cocktail glass. Run lemon peel around the rim of the glass, twist, and drop in.
