Looking over the measures here, you might think that this is a fairly small drink, and you'd be right. This isn't a pre-dinner drink, but an after-dinner one. The high amount of Benedictine in it make it relatively sweet, so a "4 ounce drink" would probably be a little too much. I'm not sure where I first found this drink, but I suspect I was trying to increase the number of Benedictine drinks in my collection.
Stir with ice.
Strain into a cocktail glass.
