Time was when I imbibed two ounces of alcohol per day. But abstemiousness has set in, and now I save the sauce for special occasions. But a favorite delivery form remains what I call the Manhattan shot.
Slam a respectably sized shot glass onto the counter. Fill it two thirds to three quarters with your bourbon of choice. Top it off with sweet vermouth, and finish it with two or three drops of Angosturo(anguish) bitters. Now, without engaging in any such tomfoolery as mixing, knock it back in one fluid gesture. Straight: no chaser, no cherry.
Repeat as necessary.
