Serving this in a martini glass without ice technically makes this a Straight Up Nail as a Rusty Nail is generally served "over" or "on the rocks", both terms for on ice. The mnemonic device bartenders use to remember the ingredients for a Rusty Nail is "shoes dummy" but since I've never attended bartending school I can't tell you why those two words would trigger the memory of scotch and Drambuie! It's an interesting fact though, huh?
Anyway, if you want to try out a scotch based classic cocktail, the Rusty Nail is a good one if you're into trying out retro cocktails!
