Bitters

Before reading Mr. Boston I had no idea what bitters were. It is a fairly potent (90-100 proof) liqueur used in small quantities (a dash or two) in a variety of old-school drinks. Being in Pennsylvania, all the liquor stores are owned by the state. Our local liquor store does not carry bitters, so I had to journey into center city today to obtain my bottle of bitters. Maybe some day I'll be able to tell the difference between a drink with a dash of bitters and a drink without, but that day is not here yet.
