Want a well balanced drink that pretty much goes with everything?  Meet the Derby.  It has nothing to do with the hat (also known as a bowler), the city in England, or the type of horse race, the most famous of which is in Kentucky.  Like the Mint Julep, the cocktail associated with the Kentucky Derby, the Derby has bourbon as its base spirit. 

1.5 ounces bourbon
.75 ounces Cointreau or Grand Marnier
.75 ounces sweet vermouth
Juice from 1/4 lime

Combine in a shaker with ice, shake as if you're off to the races, and strain into a chilled glass.  Lime garnish optional.

There are a number of versions of the Derby.  I like this one because it's simultaneously a little strong, a little sweet, and a little tart.  It is deceptively powerful.  The Derby won't smack you in the face when you taste it, but a couple of them might smack your liver.

Show your appreciation of a fine cocktail, and tip your hat to the Derby.
