My favorite mixed drink is bourbon on the rocks. Tonight it is Maker's Mark (cause that's all I have). My bourboun of choice is usually Woodford's Reserve. (For those of you who tell me that's not really a mixed drink-I say sure it is, I mixed it with ice.
I also enjoy a gin and tonic, a gin martini, and in the summer a mojito or a margarita - on the rocks with salt.
