Wow, this is darn good. I kinda wish it was a little more mustardy, even.

Didn't have any dijon mustard at the bar, but to me Amaro Sfumato Rabarbaro has always had a mustard note to it, so I tried .25 oz of that instead of the mustard and turbo.  Nice balance and interesting flavor, though the drink is a bit small with the 1 oz base.  I did it up in a coupe; not sure it would stand up to being served over crushed ice as the flavors (and proof) aren't overwhelmingly strong.  Perhaps with a short shake.
